Weaning readiness
Is my baby ready for solids?
✅ The three readiness signs (NHS)
⚠️ These are NOT readiness signs (commonly mistaken)
Getting started — practical tips
- Start with single foods. Vegetables and fruits, broccoli, sweet potato, banana, avocado, pear. Iron-rich foods are particularly important from 6 months (meat, fortified cereals, lentils, eggs).
- One new food at a time in the early days — easier to spot any reaction.
- Introduce common allergens early — peanut, egg, dairy, wheat, sesame, fish, shellfish, soya, tree nuts — by 12 months, ideally from 6 months (or 4 months in high-risk babies per LEAP / EAT). DELAYING allergens does NOT prevent allergies.
- Don't add salt, sugar, honey (under 1), or stock cubes (high salt).
- Choose: spoon-fed purée, baby-led weaning (finger foods), or BOTH — all approaches work. BLW + iron-rich foods needs particular attention.
- Continue breast / formula milk on demand. Milk is the main calorie source until 12 months.
- Sit and eat together when you can. Modelling matters more than the food itself early on.
- Mess is part of learning. Splat mats, easy-clean highchair, embrace it.
- Avoid choking hazards: whole nuts, whole grapes (quarter them), large chunks of raw apple/carrot, hot dogs, popcorn, gum, hard sweets, fish bones.
Common weaning questions
- "When should I start weaning my baby?" Around 6 months for most babies, with the three NHS readiness signs (sitting + coordination + swallowing). NOT before 17 weeks. Some babies are ready slightly earlier; some need a bit longer. Watching you eat or chewing fists are NOT readiness signs — they happen in all babies from ~4 months.
- "Will starting solids help my baby sleep?" No good evidence. The Perkin 2018 EAT trial sub-analysis found a small effect on sleep at 4-6 months. But the trade-off (starting too early when gut + kidneys + coordination not ready) outweighs any sleep benefit. Wait for the readiness signs.
- "Baby-led weaning vs purées — which is better?" Both approaches work. BLW (Baby-Led Weaning, Rapley) involves finger foods from the start; purées go through spoon-fed stages first. The BLISS trial (NZ) found no major outcome differences. Most families end up combining. Iron intake needs attention in BLW — offer iron-rich foods (meat, lentils, fortified cereal) early.
- "When to introduce peanut?" Current guidance is EARLY — from 6 months for most babies (peanut butter mixed into food, NOT whole nuts). For high-risk babies (severe eczema, egg allergy, family hx peanut allergy), discuss with GP about earlier introduction from 4 months. LEAP trial 2015 showed early peanut introduction REDUCES peanut allergy risk by ~80% in high-risk infants. Delaying does NOT prevent allergy.
- "What if my baby gags?" Gagging is a NORMAL protective reflex — different from choking. Gagging: noisy, baby moves things to the front of mouth and swallows or spits. Choking: silent, can’t breathe, going blue. Learn paediatric first aid (back blows + chest thrusts for under-1s, abdominal thrusts for over-1s). Cut high-risk foods appropriately.
- "My baby refuses solids — should I worry?" Some babies take a few weeks to engage. Keep offering without pressure; eat together; don’t replace milk feeds. Persistent refusal past 7-8 months, or weight not gaining, see your health visitor or GP — could be sensory aversion, reflux, or rarely something like FPIES.
- "How much should my 6-month-old eat?" Tiny amounts initially — a teaspoon or two. Build to 1 then 2 then 3 small meals over 4-6 weeks. Milk is still the main calorie source until 12 months. Trust your baby’s appetite cues.
- "Cow’s milk — when can I switch?" Whole cow’s milk as a MAIN drink from 12 months. Used in cooking (porridge, sauces) from 6 months is fine. Don’t use as the main drink before 12 months — too low in iron, too high in protein/sodium for that age group.
- "Vegetarian / vegan weaning?" Possible with careful planning. Iron (lentils, beans, fortified cereals, dark leafy greens + vitamin C for absorption), B12 (fortified plant milks or supplement), DHA omega-3 (algae oil supplement), calcium, vitamin D, zinc all need attention. Paediatric dietitian input is wise.
- "Vitamin drops in the UK?" NHS recommends vitamin A, C, and D drops from 6 months for breastfed babies and any baby drinking < 500 mL formula daily. Free under Healthy Start for eligible families.
- "My baby has eczema — start solids differently?" Severe eczema increases food allergy risk. NICE / BSACI: discuss early peanut and egg introduction from 4 months with your GP / paediatric allergy team. Manage the eczema aggressively (emollients + mild steroids).
- "Choking hazards I should know about?" Whole nuts (any age), whole grapes / cherry tomatoes (quarter lengthways), large chunks of raw apple / carrot, sausages / hot dogs in rounds (slice lengthways), popcorn, gum, hard sweets, fish with bones, marshmallows, lollipops. Avoid until at least 3-5 years depending on item.
- "Is it OK to skip purées entirely?" Yes — BLW is well-evidenced. Just make sure you offer iron-rich finger foods from the start, supervise closely, and learn paediatric first aid for gagging vs choking.
Educational tool only — not medical advice. If your baby is not gaining weight, has severe feeding aversion, or you have specific concerns (severe eczema, family history of food allergy), see your GP / health visitor / paediatric dietitian.
What does this mean?
The current consensus across NHS, WHO, AAP, and major paediatric bodies is to start solids around 6 months — not before 17 weeks (4 months), and with all three readiness signs present: (1) sits up and holds head steady, (2) can look at food, pick it up, and put it in their own mouth, (3) can swallow food rather than push it back out (decline of the tongue-thrust reflex). The most common mistake parents make is treating watching you eat, chewing fists, or waking at night more often as readiness signs — they’re not. Every baby does those from about 4 months as normal development. They’re fun signs of growing curiosity, not signals to start solids. The starting-solids landscape has changed in important ways in the last decade. The biggest is early allergen introduction: the LEAP trial (NEJM 2015) showed that introducing peanut early (from 4–6 months) in babies with severe eczema or egg allergy reduced peanut allergy by ~80%. The EAT trial (NEJM 2016) extended this to other common allergens. The old advice to delay allergenic foods has been completely reversed: introduce peanut, egg, dairy, wheat, sesame, fish, shellfish, soya, and tree nuts (in age-appropriate forms — e.g. smooth peanut butter not whole nuts) by 12 months, ideally from 6 months for most babies and from 4 months for high-risk babies (severe eczema, existing egg allergy, family history). The other big shift is baby-led weaning (BLW) vs purées. The BLISS trial in New Zealand found no major outcome differences between approaches — both work. Most families end up combining. BLW needs particular attention to iron (offer iron-rich foods early: meat, lentils, fortified cereals) and to paediatric first aid for gagging vs choking (gagging is a normal protective reflex; choking is silent and an emergency). Practical principles: introduce common allergens early; avoid salt, sugar, honey under 1, and known choking hazards (whole nuts, whole grapes, large chunks of raw apple); continue breast/formula milk as the main calorie source until 12 months; iron-rich foods become particularly important from 6 months as iron stores deplete; switch to whole cow’s milk as a main drink at 12 months. Babies are good self-regulators — trust appetite cues, eat together when you can, and embrace the mess.
When is my baby ready for solids?
Around 6 months for most babies, with all three NHS readiness signs present. NOT before 17 weeks (4 months).
The three NHS readiness signs
- Sits up and holds head steady (in a highchair or supported).
- Coordinates eyes, hands, and mouth — can look at food, pick it up, and get it to their own mouth.
- Can swallow food (rather than push it back out with the tongue-thrust reflex).
What is NOT a readiness sign
- Watching adults eat (every baby does this from 4 months).
- Chewing fists (developmental oral exploration).
- Waking at night more (sleep regression / growth spurt).
- Demanding bigger feeds (growth spurt).
Practical first steps
- Single foods at first — vegetables, fruits, iron-rich foods.
- One new food at a time in the early days.
- Introduce common allergens (peanut butter, egg, dairy, wheat, sesame, fish) by 12 months, ideally from 6 months.
- No added salt, sugar, honey under 1, or stock cubes.
- Sit together when you can — modelling matters.
- Continue milk feeds on demand — milk remains main calorie source until 12 months.
- Whole cow’s milk as a main drink from 12 months.
Early allergen introduction (LEAP / EAT trial era)
The LEAP trial 2015 NEJM showed early peanut introduction in high-risk babies (severe eczema, egg allergy) reduces peanut allergy by ~80%. The EAT trial 2016 extended this to other common allergens. The old advice to delay allergens has been completely reversed: introduce common allergens early, in age-appropriate forms (smooth peanut butter mixed in food, NOT whole nuts which are choking hazards).
Choking hazards
- Whole nuts (any age).
- Whole grapes / cherry tomatoes (always quarter lengthways).
- Large chunks of raw apple / carrot (steam or grate).
- Sausages / hot dogs (slice lengthways).
- Popcorn, gum, hard sweets, marshmallows.
- Fish with bones.

Frequently asked questions
When should I start weaning my baby?
Around 6 months for most babies, with all three NHS readiness signs present: (1) sits up and holds head steady, (2) coordinates eyes, hands, and mouth to pick up food, (3) can swallow food rather than push it back out. NOT before 17 weeks (4 months) regardless of signs.
What are the actual signs my baby is ready for solids?
Three readiness signs (NHS / Start4Life): sitting up with steady head control, eye-hand-mouth coordination (looking at food, picking it up, getting it to their mouth themselves), and the ability to swallow rather than tongue-thrust food back out. ALL THREE need to be present.
Why isn't watching us eat or chewing fists a sign of readiness?
Because every healthy baby does these from around 4 months as normal development. They're signs of growing curiosity and oral exploration, not signs of being physiologically ready for solid food. Treating them as readiness signs is the most common reason babies are started on solids too early.
Does starting solids help my baby sleep better?
Probably not significantly. The Perkin 2018 sub-analysis of the EAT trial found a small effect on sleep at 4-6 months in some babies. But the trade-offs (immature gut, kidneys, swallow coordination) outweigh the modest benefit. Sleep issues are usually about sleep itself — not hunger. See /calculators/sleep-regression.
Baby-led weaning vs purées — which is better?
Both work. The BLISS trial in New Zealand found no major outcome differences. BLW (Baby-Led Weaning) involves finger foods from the start; purées go through spoon-fed stages first. Most families combine. BLW needs particular attention to iron — offer meat, lentils, fortified cereals early.
When should I introduce peanut?
EARLY — from 6 months for most babies (peanut butter mixed into food, smooth not chunky, NOT whole nuts which are choking hazards). For higher-risk babies (severe eczema, existing egg allergy, strong family history), discuss with your GP about introduction from 4 months. The LEAP trial 2015 NEJM showed early peanut introduction REDUCES peanut allergy in high-risk infants by ~80%.
What foods should I avoid for the first year?
Salt and stock cubes (too much salt — kidneys can't handle); sugar (no benefit; risks dental decay); honey under 1 year (infant botulism risk); raw/undercooked eggs without British Lion mark; whole nuts (choking — but smooth peanut butter from 6 months is fine); large fish (mercury — shark, swordfish, marlin); too much oily fish (max 2 portions/week); rice milk (arsenic levels) — note: rice itself is fine in moderation.
What about common choking hazards?
Whole nuts (any age), whole grapes / cherry tomatoes (always quarter lengthways), large chunks of raw apple / carrot (steam or grate when starting), sausages / hot dogs (slice lengthways), popcorn, gum, hard sweets, fish with bones, marshmallows, lollipops. Learn paediatric first aid for gagging vs choking — they look very different and are managed very differently.
When can my baby have cow's milk?
As a MAIN drink — from 12 months (whole milk; semi-skimmed not before 2). In cooking (porridge, sauces, yogurt) — from 6 months is fine. Before 12 months as a main drink, cow's milk doesn't have enough iron and has too much protein/sodium for the kidneys.
