When Can Babies Start Solid Foods? Signs of Readiness
Updated September 2025 · 6 min read
Most babies are ready to start solid foods at around 6 months — and not before 4 months. Watch for the signs of readiness rather than the calendar: your baby can sit up with support and hold their head steady, has lost the reflex that pushes food back out with the tongue, and shows real interest in food. Breast milk or formula stays their main source of nutrition through the first year.
- Aim for around 6 months, guided by readiness signs — never before 4 months.
- Readiness = steady head control, sitting supported, interest, and no tongue-thrust.
- Milk (breast or formula) remains the main nutrition source until 12 months.
- Start with small amounts once a day and build up gradually.
Around six months is the guide
Leading health bodies recommend starting solid foods at around six months, and not before four months. By about six months, most babies have the physical skills to handle food safely and are beginning to need nutrients — particularly iron — that milk alone no longer fully provides.
Look for readiness, not just age
Age is a guide; readiness is the real signal. Wait until your baby can do all three of these:
- Stay sitting and hold their head steady — they can sit upright with support and keep their head and neck stable.
- Coordinate eyes, hands and mouth — they can look at food, pick it up and bring it to their mouth.
- Swallow food, not push it out — the “tongue-thrust” reflex that pushes food back out has faded, so food goes in rather than straight back out.
Some things that look like readiness — chewing fists, waking more at night, wanting extra milk feeds — are usually normal baby behaviour, not signs your baby needs solids.
Why not too early
Starting before four months is linked to a higher risk of choking and can displace the milk your baby still needs. A young baby’s digestive system and swallowing skills aren’t ready yet.
Why not too late
Waiting well beyond six months can mean missing out on iron and on the window to build eating skills and accept new tastes and textures. If you’re past six months and haven’t started, there’s no need to panic — just begin.
How to begin
Start with a small amount of food once a day, at a time when your baby is content rather than very hungry or tired, offering milk as usual. There’s no need to rush — the early weeks are about exploring tastes and textures, not big volumes. Always stay with your baby while they eat, and sit them upright.
