Kidy
Someone will tell you at five months that your baby "watches your plate" and it is time. Someone else will say she wakes at night because she is hungry. Neither is a sign. The short version:
- The NHS lists three main signs, best looked at together: sitting steadily with a still head, eye-hand-mouth coordination, and swallowing instead of pushing food back out
- The timing is around 6 months, per WHO, NHS, and AAP guidance
- Guidance does not put solids before 4 months, whatever her hands are doing
- Chewing fists, waking more at night, and wanting extra milk are not readiness signs. They are ordinary behaviour at that age
- Allergens go in early, not late, one at a time, as soon as solids have started
🥣 Sort the order of foods: the food introduction planner lays out the weeks by age, including when each allergen comes up.
Quick reference: readiness for solids
| Question | Short answer |
|---|---|
| When to start | Around 6 months (NHS) |
| Earliest | Guidance does not put solids before 4 months |
| How many signs | Most reliable when they show up together, not one of three |
| What is not a sign | Chewing fists, night waking, wanting extra milk |
| What to start with | A wide range is fine, with iron-rich foods going in early |
| Does milk continue | Yes, milk stays the main event through the first year |
If you are still choosing an approach, baby-led weaning vs purees compares both. For the wider picture there is the baby and toddler feeding guide.
The three signs that count
The NHS lists them together, and the "together" is the whole point. A baby with one of the three is usually not ready, just growing (NHS). Other guidance frames readiness slightly more broadly, through head and neck control, sitting with support, interest in food, and the ability to swallow, but it comes to the same thing: you are looking at a cluster, not a single item.
- She sits and holds her head steady. Upright, with minimal support. This is not about neatness, it is about safety: a head that falls forward makes safe swallowing harder
- She coordinates eye, hand, and mouth. Looks at a piece of food, reaches, grabs it, and gets it to her mouth. On her own, without your hand finishing the job
- She swallows instead of pushing out. The tongue-thrust reflex exists to protect her and fades over time. While it is working, food comes back out however many times you put it in
The third sign is the one parents most often misread. Food coming back out does not mean she dislikes the taste. It means the reflex is still there.
Three things everyone quotes that are not signs
This section is really why solids so often start too early. The NHS explicitly lists the following as not signs of readiness, even though they get read that way constantly (NHS):
| Behaviour | What it usually actually means |
|---|---|
| Chewing fists | Discovering hands and mouth, often teething too. Babies do this for months |
| Waking at night more than before | A developmental phase, a sleep regression, teeth, illness. Rarely hunger that purée fixes |
| Wanting more milk | A growth spurt. It lasts a few days and passes on its own |
Add the classic to that list: "she watches you eat". Four-month-olds watch everything, including your coffee, the cat, and the ceiling fan.
Do not start because of one good day.
Why around 6 months
Three major bodies land on the same answer, which does not happen often. WHO recommends exclusive breastfeeding for the first 6 months, then complementary foods alongside continued breastfeeding (WHO). The NHS and the AAP both point to around six months for solids (AAP HealthyChildren).
The reasons are digestive and developmental rather than calendar-based. The gut and kidneys are more mature by then, the tongue-thrust reflex has faded, and the baby has the trunk control she needs to eat safely. On top of that, iron stores built up in pregnancy start to run down for many babies around six months, so solids begin to carry a nutritional job from that point, not just a practice one.
The lower bound is firmer than the upper one. Solids do not go in before 4 months. Between 4 and 6 months it is a conversation with your pediatrician rather than a decision off a forum.
For a baby born preterm, readiness is judged on corrected age and with the pediatrician. The calendar simply does not apply there.
What week one actually looks like
Less dramatic than the internet suggests.
Days 1 to 3
- One meal a day, at a time when she is rested and in a decent mood rather than desperately hungry
- Offer a little. Literally a couple of spoons or two pieces, and that is a normal start
- Milk stays exactly the same. Nothing gets shortened, nothing gets skipped
- Expect faces. A new taste on a baby's face looks like disgust and is usually just surprise
Days 4 to 7
- Same food, or add another. It helps to get something iron-rich in among the first
- If she has refused twice in a row, leave it and try again in a few days. Do not push
- Offer a small amount of water in an open cup alongside the meal
- Different nappies in the first weeks are common
End of week one
- She genuinely swallowed something a few times → carry on at this pace
- Everything comes out every time and she is annoyed by the spoon → pause a week or two. The reflex is probably still there
In the early weeks the amounts are small and milk still carries the bulk of the nutrition. Solids are practice and the start of a nutritionally important part of the diet at the same time, iron especially.
Allergens go in early, not late
This flipped completely over the last decade or so, which is why the advice still circulating in the older generation no longer holds. Common allergens, including egg and peanut in an age-appropriate form, are introduced as soon as solids have started rather than delayed (NHS).
In practice:
- One new allergen at a time, in the morning or at midday, not in the evening
- A small amount the first time, more next time if it went well
- One at a time, so you can recognise a reaction if one shows up. Plenty of parents also leave a few days before the next new allergen, simply because it is easier to follow
- Once it has gone in, keep it in the diet regularly. Introducing and then avoiding for months is not the same as introducing
If your baby has severe eczema or an already known food allergy, discuss the order and the setting with your pediatrician first. The signs to watch for are in allergic reaction in babies.
Gagging is not choking
These two look alike to a parent watching it for the first time, and they are not the same thing.
- Gagging is usually loud. She coughs or makes noise, goes red, her eyes water, and food comes forward. It is a protective reflex doing its job
- With complete choking a child often cannot cough effectively, breathe, or make sound
Gagging is common and happens more in the early weeks of solids. Choking is an emergency. No episode has to look textbook, so treat any doubt as the serious case.
First aid steps are deliberately not written out here, because that is not something you learn from a page. What is worth doing is an infant first aid course before solids start. Half an hour you will hope never to use.
Alongside that, hard round foods stay off the menu at this age: whole grapes and cherry tomatoes (halve or quarter them lengthways), whole nuts, hard raw carrot, boiled sweets.
Common mistakes
- Starting on one sign. Sitting without the other two usually just means she learned to sit
- Cutting milk in the first weeks. Milk stays the main event through the first year. See signs your baby is getting enough milk
- Pushing when she closes her mouth. A closed mouth is an answer worth respecting, or you get a battle that runs for months
- Delaying allergens. That used to be the advice. It is not any more
- Introducing three new things on the same day. If she reacts, you do not know to what
- Honey before the first birthday. This is not about taste but about botulism risk, and the line is firm
- Judging it by how much went in. In the early weeks, anything swallowed is a bonus
When to seek professional help
A slow start to solids is not a problem in itself. Call your pediatrician if:
- she was born preterm and you are planning solids, since corrected age applies
- weight gain is poor, or she is already being monitored for growth
- she has trouble swallowing, frequent coughing, or gagging that does not ease after several weeks
- she has severe eczema or a known allergy, before allergens go in
- she is 7 to 8 months and still pushing everything back out
- you are considering solids before 4 months
- there is swelling, a whole-body rash, or difficulty breathing after a meal, which is an emergency
Your pediatrician is the one tracking growth and feeding over time, and the right first call for any of these.
Frequently asked questions
Can we start at 5 months if she sits well?
Sitting on its own is not enough, because it is most reliable when the key signs show up together. The guidance is around 6 months, and the window between 4 and 6 months is a conversation with your pediatrician. Nothing starts before 4 months.
My baby was born preterm. Do we count from birth or from the due date?
For preterm babies, readiness is assessed on corrected age and with the pediatrician, because trunk control and swallowing develop on corrected rather than calendar age. That is a conversation for a routine check, not a decision at home.
Everything I give her comes straight back out. Does that mean she dislikes food?
Usually not. The tongue-thrust reflex exists to protect her, and while it is active food comes back regardless of taste. If it happens every time, pause for a week or two and try again.
Do I have to start with purées, or can we go straight to pieces?
Both are acceptable approaches once the readiness signs are there, and plenty of families combine them. The differences, benefits, and practical traps of each are in baby-led weaning vs purees.
Does she need water once solids start?
A small amount of water in an open cup alongside meals, mostly as drinking practice. Milk stays the main source of fluid, and water comes in gradually alongside meals rather than replacing milk feeds.
How quickly should the amount increase?
More slowly than you expect, and that is fine. In the early weeks the amounts are small and grow with the interest she shows, while milk still carries the bulk of the nutrition. If she ate three spoons, the day worked.
What if she still refuses solids after a few weeks?
Pause, come back in ten days or so, and change the circumstances before you change the food: the timing, who is feeding her, whether she is sitting comfortably. If it still will not go, or you are approaching 8 months, call your pediatrician. There is more in baby refusing solids at 8 months.
How KidyGrow helps
In the first weeks of solids it is hard to tell "not ready" from "not in the mood today", because both look like a turned head. On day one the app tells you what this article tells you: one meal, milk unchanged, do not push. By day eight, with your own baby's notes behind it, the daily brief says something more specific. Something like: every meal she refused came after a nap shorter than 40 minutes, and the ones she ate came after longer ones.
A sleep-deprived parent does not remember which allergen went in on which day and how it went. The app remembers instead of you, and that is the one record you genuinely need if a reaction ever shows up.
Sometimes it finds nothing. A week with teething and a cold has no clean pattern in it for anybody.
What changes is what you bring to the next meal. Not "I have no idea whether she even likes this", but "refused twice in the afternoon, ate once in the morning, so we go in the morning".
If you are only starting to write things down, how to track feeding patterns covers what is worth logging.
