Key stages & Textures
The timeline from 0 to 3 years — How to progress step by step
Before 4 months, milk (breast milk or first-stage infant formula) is the ONLY suitable food. Never start before a full 4 months — ideally around 6 months according to the WHO/ESPGHAN 2022.
🌱 Fundamental principle
Diversification must never be forced. Each child progresses at their own pace. Milk remains the foundation until age 1. The goal is to let them discover, not to feed: the main nutritional intake remains milk throughout the first year.
📋 Summary by age range
| Age | Milk | Solid foods | Textures |
|---|---|---|---|
| 0–4 months | Exclusive, on demand | None | — |
| 4–6 months | First-stage maintained (750–900 ml/day) | Vegetables, fruits, starches, proteins (small amounts) | Smooth blended purée |
| 6–8 months | Second-stage min 500 ml/day | All groups, dairy products | Thick blend, mashed |
| 8–12 months | Second-stage min 500 ml/day | Small soft pieces, cheeses | Soft pieces |
| 1–3 years | Growth milk 500 ml/day | Adapted family meals | All textures |
4 to 6 months — The first steps
Gradual introduction • Smooth blended textures • All food groups
🍼 Milk at this age
Maintain first-stage milk. ~5 bottles/day, i.e. 750–900 ml/day. Milk remains the main nutritional foundation — solids are a discovery, not a replacement.
✅ Well-tolerated vegetables to start with
Favor mild vegetables: carrot, zucchini (without skin or seeds), pumpkin/red kuri squash, extra-fine green beans, leek (white part). Well steamed, blended smooth. Start with one vegetable at a time to spot any intolerance.
⚠️ Spinach, beetroot, chard, celeriac — Nitrate risk
These vegetables contain nitrates in high amounts, convertible into nitrites in infants → risk of methemoglobinemia (blue baby syndrome). ANSES recommendations:
- Before 6 months: to be avoided completely
- 6–12 months: maximum 1 time/week, small amount, eaten within 24h after cooking (never reheat)
- Prefer commercial baby food jars for these vegetables (nitrate content regulated and controlled)
- Discard the cooking water. Never keep more than 24h in the refrigerator or reheat leftovers
- Seasonal spinach (April–November): lower nitrate content
⚠️ Fermentable vegetables — Gradual introduction
Cabbages, broccoli, bell pepper, onion, garlic : fermentable, can cause gas and pain. Introduce gradually in small amounts. Tomato : acidic, cook and blend without skin or seeds. Mushrooms : after 8 months, very well cooked. Avocado : can be offered raw and mashed from 4–6 months (rich in good fats).
🧀 Dairy products (4–6 months)
A few teaspoons of plain yogurt or fromage blanc. Occasionally: grated cheese in a purée. No pure cow's milk before 1 year. 150–200 ml milk = 1 yogurt (125 g) = 20 g cheese. Never 0%, skimmed or semi-skimmed products.
Pasta, rice, semolina, potato: no particular restriction. Mix with vegetables (¼ starches + ¾ vegetables). Gluten-free flours before 6 months (rice, corn). Gluten allowed from 4 months, even with a family history of celiac disease (do not delay). Bread : after 6–7 months. Do not add salt.
⭐ Introduce ALL allergens from the start of diversification
PNNS4 (2021) and ESPGHAN 2022 recommend introducing all food groups, including major allergens, from 4–6 months, even in children with a family risk. Delaying introduction increases the risk of allergy (LEAP study 2015).
- Peanuts (groundnuts) : as a purée or peanut butter (never whole before 5 years). Introduce from 4–6 months, including in children with eczema (after medical advice). Documented preventive benefit.
- Tree nuts : as a purée (almond, hazelnut, cashew). Never whole before 5 years.
- Egg : well cooked (hard-boiled). Introduce from 4–6 months.
- Fish : from 4–6 months, uncontaminated species.
- Cow's milk / dairy products : yogurt, cheese from 4–6 months.
- Wheat / gluten : from 4 months, gradually.
- Sesame : possible as a paste (tahini) from the start of diversification.
- If a family history of severe allergy: consult before introduction, but do not avoid.
Absolute prohibitions: Salt · Added sugar · Honey (before 1 year) · Pure cow's milk · Plant-based drinks · Raw shellfish · Raw-milk cheeses · Whole nuts · Raw, smoked or undercooked fish · Preparations made with raw egg
6 to 12 months — Exploration
Varied textures • Increasing quantities • Small soft pieces
✅ All vegetables can be introduced
Variety is key. Offer new vegetables regularly: broccoli, cauliflower, beetroot, peas, artichoke, fennel, asparagus, mushrooms (well cooked). Textures gradually less smooth, then soft pieces.
⚠️ Spinach, beetroot, chard — Nitrate precaution maintained until 12 months
- Maximum 1 time/week in small amounts until 1 year
- Eat within 24h after cooking — never reheat or keep more than one day
- Always discard the cooking water
- After 12 months: restriction lifted, these vegetables can be eaten normally
⚠️ Raw vegetables and textures — Choking caution
Raw vegetables can be offered from 9–10 months in soft pieces. Whole raw carrot: forbidden (choking hazard) — grated only or cooked soft. Cherry tomatoes: cut into quarters. Mushrooms: always well cooked.
| Age | Dairy product | Quantity / Texture |
|---|---|---|
| 6–8 months | Plain yogurt or fromage blanc | A few tsp at the afternoon snack. Plain, unflavored, whole. |
| 8–10 months | Soft cheese (brie, pasteurized camembert) | ~20 g — small soft piece. Never raw milk. |
| 10–12 months | Hard cheeses (emmental, comté, edam) | ~20 g in a small piece. Gradually firmer textures. |
| 6–12 months | Second-stage infant milk (and/or breast milk) | Min 500 ml/day — max 800 ml/day (all dairy products included) |
⚠️ 0%, skimmed or semi-skimmed products: not suitable before 3 years. No pure cow's milk before 1 year. No raw-milk cheese before 3 years.
Still forbidden: Salt · Added sugar · Honey (before 1 year) · Pure cow's milk · Plant-based drinks · Raw-milk cheeses · Raw/smoked/undercooked fish · Whole nuts · Mercury-contaminated fish · Raw egg
1 to 3 years — The family table
Varied and balanced diet • All textures • Appropriate portions
✅ All vegetables and fruits allowed after 1 year
The restriction on spinach, beetroot, chard (nitrates) is lifted after 12 months. All vegetables can be eaten according to appetite, raw or cooked, in all textures. Vary colors and seasons, organic and local if possible.
⚠️ Textures: choking caution until 5 years
- Grapes, cherries, cherry tomatoes: cut lengthwise into quarters until 5 years
- Apples, raw carrots: in thin slices or grated, never in whole round pieces
- Walnuts, almonds, hazelnuts: whole forms strongly advised against before 5 years (choking). As a purée (almond butter, peanut butter): possible from 1 year if no allergy
- Sweets, chewing gum: forbidden before 5 years
| Product | Equivalent | Advice |
|---|---|---|
| Growth milk ⭐ | 200 ml = 1 portion | Fortified with iron, DHA, vit D. First choice if diet is not very varied. |
| Whole UHT milk | 200 ml = 1 portion | OK if diet is varied. Cheaper, not fortified. |
| Whole plain yogurt | 1 pot (125 g) | Plain, unflavored. Alternate with fromage blanc. |
| Whole fromage blanc | 150 g | Plain. Replaces 1 portion of milk. |
| Cheese (emmental, comté) | 20–30 g | All textures. No raw-milk cheese before 3 years. |
| Powdered milk (milk refusal) | 1 scoop/30 ml | In purées, soups, cakes. Properties retained. |
🚫 Semi-skimmed, skimmed, 0% milk = not suitable before 3 years

- Powdered milk mixed into purées, soups, cakes (1 level scoop per 30 ml of water). All nutritional properties are retained.
Milks compared after 1 year
Growth vs Whole vs Semi-skimmed — What to choose?
✅ Growth milk (1–3 years)
- Fortified with iron (deficiency common at this age)
- Fortified with DHA (neurodevelopment)
- Fortified with vitamin D and A
- Adapted to the needs of 1–3 years
- Limited in protein (kidney-sparing)
- More expensive than whole milk
✓ Whole UHT milk (from 1 year)
- Lipids suited to brain growth
- Natural fat-soluble vitamin A
- Quality proteins
- Cheaper
- Not fortified with iron or DHA
- Sufficient if diet is varied
❌ Semi-skimmed or skimmed milk
- Insufficient in essential lipids
- Too low caloric intake
- Deficit in vitamins A, D, E, K
- Low in DHA
- May promote an energy deficit
💡 Practical rule: 150–200 ml of milk = ?
1 plain yogurt (125 g) or 150 g of fromage blanc or 20 g of cheese (emmental, comté) = 1 portion of milk in calcium equivalent.
Breastfeeding
Specifics during food diversification
🌟 Principle
Breastfeeding is compatible with diversification and can continue as long as desired. It offers unique nutritional and immunological benefits. The WHO recommends continuing until 2 years and beyond.
⏰ When to start?
Exclusive breastfeeding recommended until 6 months (WHO). Diversification possible from 4 months if signs of readiness. Between 5 and 6 months is often ideal with breastfeeding.
📏 Volumes and frequencies
No precise measurement. Feeds on demand. Start of diversification: solids after the feed. From 6–8 months: solids before to stimulate the appetite.
☀️ Vitamin D essential from day 4
Breast milk contains <25 IU/L. Mandatory supplementation from day 4: 400 IU/day (SFP 2022), no difference in dose from bottle-fed children. Medicines with marketing authorization (AMM) only (Adrigyl®, Zymad®, Stérogyl®). Never dietary supplements bought on the internet.
🩸 Iron: caution from 6 months
Birth reserves depleted around 4–6 months. Breast milk is low in iron (good bioavailability). Introduce meats, fish, legumes early.
🥛 No infant formula required
No need for infant formula if diversification is well conducted. After 1 year and weaning: growth milk or whole UHT milk.
🥗 The mother's diet
Varied diet. Avoid alcohol and tobacco. Maternal DHA supplementation recommended (200 mg/day). Adequate iodine intake (fish, iodized salt): the iodine in breast milk depends directly on the mother's intake. If the mother follows a vegan diet: B12 supplementation is mandatory.
📅 Duration and weaning
WHO: continue until 2 years and beyond. Gradual weaning. No abrupt weaning except for medical contraindication.
🤧 Allergies: introduce early
Breastfeeding does not contraindicate the early introduction of allergens — on the contrary, it is recommended from the start of diversification.
Infant cereals
With or without gluten? When? How much?
❓ Are infant cereals essential?
No. Pasta, rice, bread, semolina are perfectly fine if properly blended. Infant cereals can be useful to thicken purées or bottles in infants who get hungry quickly. They provide iron and B-group vitamins.
Rice, corn, tapioca
1–2 tsp
(bottle or purée)
Wheat, barley, oats
Small progressive amounts
Do not delay!
Iron-fortified ++
2–4 tsp/meal
or bottle
Bread, pasta, rice
Prefer wholegrain
Limit if very sweet
⚠️ Gluten: do not delay!
According to ESPGHAN 2022 and AFPSA, gluten introduction should not be delayed, even in children with a family risk of celiac disease. Introduce between 4 and 12 months, gradually. Delaying gluten increases the risk of celiac disease.
📏 Practical quantities
- In a bottle: 1 to 2 tsp max to keep an appropriate flow. Do not exceed 4 tsp.
- In a purée: 1 to 2 tsp to thicken to the desired consistency.
- Iron-fortified flours to be favored after 6 months (needs: 8 mg/day between 6 and 12 months).
- Increase gradually according to appetite. Never force.
Vitamin D
Routine supplementation from birth to 5 years
Why supplement routinely?
Vitamin D is essential for bone mineralization, immunity and neurodevelopment. In France, sunlight is insufficient and diet alone does not meet the needs. Supplementation is mandatory from birth until 18 years (SFP/AFPA/GFHGNP, consensus Bacchetta et al. Archives de Pédiatrie 2022). Without a supplement, up to 50% of children are deficient in winter.
Medicines only — never dietary supplements. Cases of severe hypercalcemia have been reported with dietary supplements bought on the internet, dosed at 10,000 IU/drop (instead of 300 IU/drop). Use exclusively medicines with marketing authorization (AMM) (Adrigyl®, Zymad®, Stérogyl®). Do not combine several sources.
All children, breastfed or not, regardless of ethnicity. Daily drops. Start by day 4 at the latest.
Daily OR at the start and end of winter: 80,000–100,000 IU (Uvedose®). No 200,000 IU doses (to be avoided).
Dark skin, premature <35 weeks GA, little sun exposure, obesity, vegan diet. Or 50,000 IU/6 weeks. Check 25(OH)D if in doubt (target: 50–120 nmol/L).
Breast milk contains <25 IU/L. Supplementation imperative from day 4. No difference in dose from bottle-fed children (SFP 2022 recommendation).
| Medicine | Dose/drop | 400 IU/day schedule | Use |
|---|---|---|---|
| Adrigyl® (D3) | 333 IU/drop | 1 to 2 drops/day | From birth — reference medicine |
| Zymad® (D3) | 300 IU/drop | 1 to 2 drops/day | From birth |
| Stérogyl® (D2) | 400 IU/drop | 1 drop/day | From birth. D2 = ergocalciferol |
| Deltius® (D3) | 400 IU/drop | 1 drop/day | From birth |
| Uvedose® (D3) | 100,000 IU/ampoule | 1 ampoule in Nov. + 1 in Feb. | ≥ 18 months only — avoid before |
💊 Practical details
- Preferably administer with a meal containing fats (improved absorption)
- Drops: directly in the mouth or in a spoonful of milk/purée
- Do not stop in summer — sun exposure of infants in strollers is insufficient
- Growth milk contains ~150–200 IU/L: insufficient on its own to meet the needs
- Never dietary supplements bought on the internet — documented risks of serious overdose (ANSM/ANSES 2021)
Autonomy & DME
Baby-Led Weaning — motor stages and safety
🧠 What is DME?
Baby-Led Weaning (Diversification Menée par l'Enfant) consists of offering foods in pieces as soon as the child can grasp them, alongside or instead of purées. A safe and scientifically validated approach. Benefits: better regulation of satiety, reduced risk of overweight, decreased neophobia, development of fine motor skills.
Holds their head. Opens their mouth. Follows food with their eyes. → Smooth purées by spoon. DME not applicable.
Sits with support. Brings objects to the mouth. → Start of DME: soft steamed vegetable stick, slice of ripe fruit.
Palmar grasp. Bites and breaks food apart. → Soft bread, soft vegetables, soft cheese. Direct supervision mandatory.
Thumb-index pincer grasp. Great autonomy. → Varied small pieces, finger foods, eats alone. Spoon offered.
Uses a spoon. Eats independently. → Adapted family meals. Let them eat alone even if messy!
Eats alone with spoon and fork. Expresses their tastes. → Offer choices, respect preferences.
⚠️ Absolute safety rules
- Always in a seated position — never lying down or semi-reclined
- Constant supervision — never leave alone
- Avoid: whole small round fruits (grapes → cut lengthwise into quarters), whole nuts, raw carrots, sweets, whole cherry tomatoes
- Learn pediatric first-aid maneuvers (choking)
Difficulties & Food refusal
Neophobia, ARFID, selectivity — understanding and acting
🙈 Food refusal and neophobia (NORMAL)
The food neophobia (fear of new foods) is normal and almost universal between 18 months and 3–4 years. A child may refuse up to 15 to 20 presentations before accepting. It is not a tantrum, it is an evolutionary protective mechanism.
What to do? Offer without pressure, without forcing, without negotiating. Place it on the plate even if refused. Encourage curiosity ("you can just smell it / touch it"). Never force, threaten or reward. Eating as a family is the best model.
🚨 Severe food phobia — ARFID
ARFID (Avoidant/Restrictive Food Intake Disorder) is a severe disorder: extreme food restriction, fewer than 5–10 accepted foods, significant distress, impact on weight.
Warning signs: <5 accepted foods after 3 years, growth-curve drop, major anxiety at mealtimes, absolute refusal of new textures.
Referral: pediatrician/child psychiatrist, speech therapy if oral-feeding disorders, specialized dietitian. Do not wait.
📋 Food selectivity — The Ellyn Satter rule
Division of responsibility: the parents decide what, when and where ; the child decides how much and whether they eat.
• Do not prepare separate meals at the request of the selective child.
• Always 1 "safe" (accepted) food per meal + also present the new ones.
• Involve the child in preparation: sensory exposure outside mealtimes reduces fear.
• No screens at mealtimes. A skipped meal is not a problem — do not compensate with an immediate bottle.
😭 Crying and refusal of the bottle / spoon
• Spoon refusal before 4–5 months: normal (extrusion reflex active).
• Bottle refusal in a breastfed child: sippy cup or glass from 6 months; let someone else give the bottle.
• Milk refusal after 1 year: substitutes (yogurt, cheese, powdered milk in dishes).
• Crying at mealtimes: check for hunger, fullness, pain (reflux, ear infection), tiredness, positional discomfort.
⚖️ A child who does not eat "enough"
After 1 year, growth slows physiologically and appetite decreases — this is normal. Caloric needs at 1–2 years: only ~1,000–1,200 kcal/day.
Monitor the weight/height curve. A steady curve is reassuring even if quantities seem low. Consult if there is a drop in the curve or worrying behavior.
🤮 Gagging and vomiting at mealtimes
The gag reflex is much more forward in infants: it is a normal protection. It gradually moves back with exposure to textures — do not interpret it as an intolerance.
Continue to gently offer the same textures in small amounts. Distinguish from pathological GERD (medical consultation if persistent).

Vegetarian & vegan diets
GFHGNP 2022 recommendations — Deficiencies that must be prevented
The vegan diet is strongly not recommended in children under 3 years by the GFHGNP (2022), because of the risk of serious deficiencies that can lead to growth retardation, irreversible neurological disorders, rickets. If such a diet is maintained, close medical and dietary follow-up is essential.
✅ Possible with caution, few major risks
Eggs and dairy products cover most needs. No routine mandatory supplementation beyond the universal vitamin D. Monitor:
- Iron: less bioavailable in plants. Combine vitamin C with meals to improve absorption. Legumes, fortified cereals. Ferritin test if in doubt.
- Omega-3 DHA: absence of oily fish. Compensate with flaxseed, walnut, rapeseed oil. Consider algae-derived DHA supplementation if no fortified eggs.
- Zinc: less bioavailable in the plant kingdom. Legumes, wholegrain cereals, pumpkin seeds.
- Iodine: intake often insufficient without fish/shellfish. Use iodized salt (caution with amounts) or medical supplementation if necessary.
- Vitamin D: 400 IU/day as for all children (SFP 2022).
🚨 Unavoidable multiple deficiencies — medical follow-up mandatory
A strict vegan diet cannot meet all the needs of a growing child without rigorous supplementation. Documented deficiencies:
- Vitamin B12: totally absent in plants. Mandatory supplementation as soon as breast milk or infant formula is stopped. Dose: 5 µg/day (6 months–3 years). Never spirulina (B12 not bioavailable). Risk of irreversible brain atrophy if deficient.
- DHA: algae supplementation (algae-derived DHA) recommended.
- Calcium: supplementation if no longer on infant formula. 250–500 mg/day depending on dietary intake.
- Vitamin D: 800 IU/day (risk-factor dose — SFP 2022). Prefer D2 (ergocalciferol, Stérogyl®) or vegan D3.
- Iron, zinc, iodine: to be assessed individually. Follow-up blood tests recommended.
🍼 If breast milk is refused or no breastfeeding on a vegan diet
Commercial plant-based drinks (soy, almond, oat…) are unsuitable even when fortified. The only acceptable formulas are infant formulas based on hydrolyzed rice protein (if allergic to cow's milk protein):
- Prémiriz® first-stage / second-stage (Picot): rice-based formula, formulated according to European standards
- Modilac Expert Riz 1® / 2® / 3®, Novalac Riz® : formulas based on hydrolyzed rice
- These formulas provide iron, vitamins, essential fatty acids, limiting the risk of deficiency
- 500 ml/day recommended until 3 years to ensure basic nutritional intake
📋 Recommended medical follow-up on a vegan diet
Blood tests to consider: CBC, ferritin, phosphocalcic panel, serum zinc, active vitamin B12 (holotranscobalamin), 25(OH)D, TSH + free T4 (iodine). Consultation with a specialized dietitian. Monitoring of the height-weight curve every 2–3 months before 2 years.
