Weaning — the transition from milk to solid food — is one of the most anticipated milestones in baby’s first year. It is also one of the most overlooked with conflicting advice: start at 6 months or at 5? Purees or finger foods? Grains first or vegetables? The choices can feel overwhelming. This guide cuts through the noise with current UK and European guidance — clear, evidence-based advice on starting weaning UK safely and confidently.
When to Start: The 6 Month Guideline
The current UK NHS and WHO recommendation is to wait until around 6 months before introducing solid foods. This is not an arbitrary age — it corresponds to when most babies develop the physical and neurological maturity needed to safely process solid food; the ability to sit with support, have good head control, and lose the tongue-thrust reflex that pushes food back out.
While some European countries (including some Scandinavian nations) permit introduction from 4–6 months under certain circumstances, the majority of European paediatric guidance and WHO align on 6 months as the target. The NHS is clear: do not start before 17 weeks (4 months) under any circumstances as the gut and renal system are not mature enough to handle solids.
Signs your baby may be ready to start:
- Sitting upwith minimal support and holding head steady
- Showing interest in food — watching you eat, reaching towards food
- Losing the tongue-thrust reflex and moving food forward in the mouth
Note: teething, waking in the night, or seeming hunger are not reliable indicators of readiness.
Safety First: Reducing Choking Risk
Choking is one of the most common fears parents have about starting solids. While no approach eliminates the risk entirely, several steps minimise it:
- Always supervise baby during all meals
- Ensure baby is sitting upright, never reclined or strapped in a car seat
- Cut foods into finger-length strips that can be grasped; avoid small round circular pieces that fit exactly in the throat
- Avoid whole nuts, grapes, raw carrots, and other choking hazards before age 5
- Learn baby First Aid covering baby choking response — the British Red Cross and St. John Ambulance offer free online guidance
Note that gagging is normal and different from choking. Babies have a higher gag reflex than adults as a protective mechanism. Gagging may look alarming but is typically effective and does not require intervention.
What to Offer First
There is no one right first food, but the NHS recommends:
- Soft cooked vegetables: parsnip, broccoli, sweet potato, and carrot are ideal starters
- Fruits: mashed or softly cooked apple, pear, or banana
- Starchyfoods: potato, rice, pasta, or bread (all rich in carbohydrates needed for growth)
- Protein: pureed legumes, fish, egg, or meat — key for iron intake as baby’s fetal stores run low after 6 months
NHS advice is to start with a wide variety rather than sticking to a single food for days, as this promotes acceptance of variety. Baby-led weaning (BLW) and traditional purees are both acceptable — there is no evidence one is superior for long-term outcomes when used appropriately.
Foods to Avoid Before 12 Months
- Honey: risk of Clostridium botulinum spores
- Added salt or sugar: renal system is not mature enough to process high salt loads
- Cow’s milk as a drink: can be used in cooking after 6 months but should not replace breast or formula milk as a drink before 12 months
- Certain fish: avoid shark, swordfish, and marlin due to high mercury content
- Rawor not-fully-cooked eggs: avoid raw eggs (however, well-cooked eggs are ok and recommended for early allergen introduction)
Introducing Top Allergens Early
This is one of the most significant shifts in weaning advice in recent years. Both the NHS and NICE now recommend introducing common allergens (peanuts, egg, cow’s milk, wheat, soy, sesame) from around 6 months, not delaying them. Evidence from studies including the LEAP trial shows that early introduction reduces the risk of developing peanut and other food allergies by up to 80%. Introduce one new allergen at a time, in a small quantity, and wait a few days before introducing another. If your baby has moderate-to-severe eczema, speak to your GP first as they may want to advise on sequencing.
Frequently Asked Questions
Should I start with rice cereal?
Rice cereal was once standard advice but is no longer actively recommended by the NHS or most European paediatric bodies. The focus now is on a broad variety of tastes and textures, including iron-rich foods.
My baby seems hungry at 4 months — should I start solids earlier?
No. Hunger at 4 months is more likely to be a growth spurt or a feeding pattern issue. The NHS recommends frequent feeding on demand and does not support early introduction of solids as a solution to hunger.
Can I add spices and herbs to my baby’s food?
Yes. The NHS suggests garlic, mild spices, and herbs are all fine ad in excellent condition. Babies have a natural drive to eat what you eat; trust them, and trust yourself.
