When Is My Baby Ready to Start Solids?

Updated 11 October 2026

The short answer

Most babies are ready to start solid food at around 6 months, which is when the NHS and the World Health Organization recommend starting. Look for three signs together: your baby can sit up and hold their head steady, can look at food, pick it up and bring it to their mouth, and can swallow food rather than pushing it straight back out with their tongue. Until then, breast milk or first infant formula gives them everything they need.

Why around 6 months?

By about 6 months most babies' digestive systems and swallowing skills have matured enough to handle food other than milk. It's also when the iron a baby was born with starts to run low, so they begin to need iron from food. Starting much later can make it harder for them to get enough iron and to accept new textures.

"Around 6 months" is a guide, not a deadline. Babies develop at different speeds, and the signs matter more than the date on the calendar.

The three signs to look for

Health visitors look for all three of these together, not just one:

• Sitting with good head control. Your baby can stay in a sitting position, with a little support if needed, and hold their head steady.
• Coordination. They can look at food, reach for it, pick it up and put it in their mouth by themselves.
• Swallowing, not just spitting out. The early tongue-thrust reflex, which pushes food back out, has faded. They can move food to the back of their mouth and swallow it. Babies who aren't ready push most of it back out, however many times you offer it.

It can take a few days of trying before you can tell whether your baby is swallowing food or mostly pushing it out. If it's mostly coming back out, it's fine to stop and try again in a week or two.

Signs that aren't readiness

These behaviours are often taken as a baby being ready for solids, but they're normal at this age and aren't signs on their own:

• Chewing their fists or toys, usually teething or exploring.
• Waking more at night. Sleep changes have many causes, and solids don't reliably fix them.
• Wanting extra milk feeds, often a growth spurt, best met with more milk.
• Watching you eat with interest, a normal stage of curiosity, but not enough alone.

Can I start before 6 months?

Don't give solid food before your baby is 17 weeks (about 4 months) old. Their gut and swallowing aren't ready. If you're thinking of starting before 6 months, for example because your baby seems very hungry or has reflux, talk to your health visitor or GP first. If you do start a little early, there are extra foods to avoid at that age, including wheat, eggs, nuts, seeds, fish and shellfish, soft and unpasteurised cheese, and cow's milk.

What if my baby was born early?

For babies born prematurely, readiness is usually judged using their adjusted age (counted from their due date) together with the developmental signs above, and the right timing can vary more. Your health visitor or neonatal team can advise on when to start and what to offer first.

What if my baby is past 6 months and not showing the signs?

Some babies take a little longer. Keep offering opportunities, such as sitting with you at mealtimes and trying a few soft foods. If your baby is approaching 7 months and still isn't sitting steadily, isn't bringing things to their mouth, or can't seem to swallow food, mention it to your health visitor or GP. Delaying solids too long can make it harder to meet iron needs and to accept textures.

What the first weeks look like

• Start small. A few teaspoons or a few soft finger foods, once a day, at a time when your baby isn't too tired or too hungry. Many parents offer solids an hour or so after a milk feed.
• Keep milk the main food. Breast milk or formula is still most of their nutrition. Solids are extra at this stage, not a replacement, and you don't need to cut down milk feeds to make room.
• Build up gradually. Over the following weeks, move towards two and then three small meals a day.
• Go for variety, early. Vegetables (including bitter ones like broccoli), fruit, and iron-rich foods such as meat, fish, eggs, lentils and beans. There's no need for a strict order of foods.
• Introduce common allergens one at a time, from around 6 months, watching for a reaction. See how to introduce allergens safely.
• Offer water in an open or free-flow cup with meals.
• Move on from smooth textures fairly soon. Within the first few weeks, offer mashed and lumpier food and soft finger foods too. See weaning textures by stage.

Not sure whether to start with spoon-feeding or finger foods? Baby-led weaning vs. purées compares the two. Both are fine, and many families combine them.

Frequently asked questions

What are the signs a baby is ready for solid food?

There are three, and you're looking for all of them together: your baby can sit up and hold their head steady, can look at food, pick it up and bring it to their mouth, and can swallow food rather than pushing it back out with their tongue. Most babies show these at around 6 months.

Is 4 months too early to start solids?

The NHS and WHO recommend waiting until around 6 months. Solid food should never be given before 17 weeks (about 4 months). If you're considering starting before 6 months, speak to your health visitor or GP first.

Will starting solids help my baby sleep through the night?

There's no good evidence that it does. Waking at night is common at this age for many reasons, and it isn't a sign of readiness for solids on its own.

How much food should my baby eat when starting solids?

Very little at first, sometimes just a taste. In the early weeks solids are about learning to eat, while milk still provides most nutrition. Amounts grow gradually. See how much a baby should eat.

Should I give milk or solids first?

At the start, many parents offer solids a while after a milk feed, when their baby is interested but not desperately hungry. Either way, keep giving breast milk or formula as usual. Solids are added on top in the first months.

What should my baby's first foods be?

There's no single right first food. Soft cooked vegetables, fruit, and iron-rich foods like lentils, meat, fish or egg are all suitable from around 6 months. Avoid salt, sugar, honey and whole nuts. See foods to avoid before 12 months.
