Starting baby-led weaning: the first few weeks

Starting solids is a milestone, and it is a slower, messier one than most people expect. For the first few weeks your baby is learning to handle food rather than eating it, and milk is still doing the feeding — so there is far less riding on any single meal than it feels like at the time.

This is not clinical guidance, and Nourishible is not a paediatric dietitian. The rules quoted below come from the NHS and are named as such. Check with your health visitor or doctor about what is right for your baby, and read the NHS weaning guidance on allergens and choking hazards before you start.

How do you know your baby is ready?

The NHS describes three signs, and they arrive together rather than one at a time — the common mistake is treating sitting up on its own as enough.

1. They can stay sitting and hold their head steady. A supportive highchair counts; they do not need to sit unaided on the floor. What matters is that they are upright rather than reclined and the head does not loll. If they need cushions wedged around them to stay up, they are not there yet.
2. They can coordinate eyes, hands and mouth. They look at food, pick it up, and take it to their mouth without you guiding their hand. This is the one people most often skip past, and it is the one that makes self-feeding possible at all.
3. They can swallow food rather than push it back out. Early on, the tongue-thrust reflex pushes most things straight back out. When food starts staying in and going down, that reflex has faded.

These usually turn up around six months, which is when the NHS advises starting solids. Waiting for the signs matters more than hitting the date exactly — but there is a floor as well as a target: UK and Irish health services both advise that solid food should not start before seventeen weeks, or four months, whatever a baby seems to be doing. Before then, milk is all they need, and solids displace nutrition rather than adding to it. If your baby looks ready well before six months, that is a conversation with your health visitor rather than a green light.

What looks like readiness but is not?

Three things, and all of them are completely normal at this age:

• Chewing their fists
• Waking in the night when they had been sleeping through
• Wanting extra milk feeds

None means your baby needs solids yet, and between them they are the most common reason families start early.

If the signs have not all arrived, a short wait is normal — though if your baby is past six months and they still are not there, mention it rather than waiting on.

If your baby was born prematurely, readiness is assessed on corrected age — their age counted from the due date rather than the birth date. NHS guidance for babies born early puts the usual window at around four to six months corrected age, alongside the same readiness signs, and is explicit that delaying solids without a clinical reason makes it harder for a child to accept new textures later.

Preterm babies also start with smaller iron stores and are often already on a prescribed supplement, so do not start or stop one without asking. Timing here is worked out individually — your neonatal team or health visitor is the right person to ask, and this is one of the situations where a website genuinely cannot answer it.

What should you offer first, and how often?

Start with vegetables that are not so sweet — broccoli and cauliflower — cooked soft enough to mash or squash. Leafy greens like spinach are usually held back a little later; many sources put them after six months because of their naturally higher nitrate content, so it is not the top of the list for a first meal. To begin with, your baby only needs a small amount of solid food once a day, and milk remains their main source of nutrition through the first year.

That is the NHS position, and it is deliberately unfussy. There is no order you have to follow and no list you have to work through. The simplest approach is to cook what you were already cooking and lift out your baby's portion before you season it.

For which specific foods to start with, each with its nutrition and the rules that apply, see the first foods index. Two nutrients change around now and have guides of their own: iron, which has to start coming from food, and vitamin D, which does not come from food at all.

What do the first few weeks actually look like?

What to expect, not what to do. These stages blur into each other and every baby runs to their own timetable.

The first week. Almost nothing gets eaten, and for most babies that is what this week looks like. Your baby is working on sitting, holding, and getting something to their mouth. Milk is still providing nearly all their calories, so an uneaten meal is not a problem. Crying in a highchair in week one is ordinary and not a sign to stop.

Weeks two to four. A little more goes in, though still not much. You will see strong opinions that reverse themselves a week later — a food refused several times and then happily eaten later is completely ordinary, and offering it again without pressure is the usual advice. Expect to find recognisable food in their nappy; at this stage that is normal and not a sign anything is wrong.

Around two to three months in. Meals start to look like meals, and a rhythm settles in around milk feeds rather than replacing them. Somewhere in here you will usually see their grip change — from a whole-fist grab to finger and thumb — which makes smaller pieces easier for them. No need to stop offering strips; offer both.

How much should they be eating?

There is no published amount, and the range between perfectly normal babies is enormous — which is genuinely why nobody prints a number, rather than anyone being coy about it.

What matters is not how much goes in on a given day but the direction over a month: more interest, more textures, more of the meal ending up inside them rather than on the floor. If your baby is gaining weight and having plenty of wet nappies, the amount is fine.

What should you do at the table?

Less than you think. The commonest thing to go wrong in month one is not choking — it is the adult hovering, spoon-feeding and scraping the chin.

• Before anything goes on the tray, check the size and shape — finger-length strips at six months, soft enough to squash between your thumb and forefinger. The safety guide has the shapes to avoid.
• Put the food down and let them get it themselves. Loading a piece and handing it over is fine; putting it in their mouth is not.
• For anything wet — yoghurt, porridge, lentils, hummus, fortified cereal — load a spoon and hold it out handle-first for them to take. That is still self-feeding, and it is how anything that will not hold its shape gets into a six-month-old.
• Do not pull food out when they gag. Let the reflex finish the job.
• Eat your own meal at the same time. Babies copy, and a parent watching intently while they eat nothing makes mealtimes tense.
• Offer food about half an hour to an hour after a milk feed. A ravenous baby has no patience for learning; a completely full one has no interest.
• Cook the family meal, take the baby's portion out before you salt it, then season yours at the table.
• Stop when they tell you they are done — and they tell you with their body, not the plate. Turning away, leaning back or arching, batting your hand aside, sealing their lips, or starting to drop food over the side rather than explore it: the meal is finished, even if barely anything went in.
• Take the food away without a last try. One more mouthful after they have said no is what teaches a baby to stop trusting their own appetite, and it is the hardest habit to undo later.

What do you actually need to buy?

Very little, and you can start tomorrow with what is already in your kitchen.

• A chair your baby can sit upright in, with their feet supported. Foot support matters far more than what the chair cost — stable feet help them stay steady and upright, which is the position you want them eating in.
• A wipeable mat under the chair. The single biggest reduction in cleanup effort.
• Bibs with sleeves, more than you think.
• Genuinely nothing else in the way of equipment. Special bowls, spoons, moulds and pouches are lovely if you want them, but they mostly solve problems you do not have yet.

When should you ask someone?

Most of weaning needs nobody but you. These are the exceptions, and they are not all equally urgent — which is the part most lists leave out.

Call 999 if, after a food, your baby has swelling of the lips, tongue or face · noisy, wheezy or difficult breathing, or a hoarse cry · sudden widespread hives or swelling · repeated vomiting alongside any of these · going pale, floppy or hard to rouse.

This can be a serious allergic reaction and needs treating straight away. Keep them lying flat or on their side while you wait — do not sit or stand them up. Do not give an antihistamine and wait to see, do not drive to A&E yourself, and stay on the line even if they seem to improve. Choking on the food itself is also 999 and looks different — the safety guide covers how to tell.

Same day, via your GP or 111: blood or persistent mucus in their stools, repeated vomiting after a particular food, weight loss or no weight gain, a baby who has become reluctant to feed, or eczema that is getting worse.

Your health visitor, in the ordinary way: a baby who still cannot manage any texture after two months of trying · gagging that is no better after six to eight weeks · a baby who has refused nearly everything for two weeks or more having previously eaten · or anything you would simply like a second opinion on.

The short version

Wait for all three readiness signs rather than the birthday, and never start before seventeen weeks. Offer one small meal a day of soft, finger-sized pieces, and expect almost none of it to be eaten for a while. Sit on your hands, eat your own lunch, and stop when they say stop. Milk is still doing the work. Before the first meal, read the safety guide — the difference between gagging and choking is the one thing genuinely worth knowing in advance.
