Starting solids: when, how and what to offer first

Starting solids is less about a date on the calendar and more about three skills your baby shows at the same time.

In short

Most babies are ready for solid foods at around 6 months. WHO, the NHS, the AAP and the CDC all point to about 6 months, and the European paediatric society ESPGHAN says never before 4 months and no later than 6. Look for three signs together - sitting with a steady head, picking food up and bringing it to the mouth, and swallowing rather than pushing food out.

When to start: what the guidelines actually say

Four major bodies agree on the broad picture and differ on the details. Here is what each one says, side by side.

Organisation	When to start solids	Key nuance
WHO (2023 guideline)	Complementary feeding generally starts at 6 months	Covers children 6-23 months worldwide
NHS (UK)	Around 6 months	Wait even if a jar says "from 4 months"
AAP (US)	Breast milk only for about 6 months, then foods alongside it	Readiness depends on each baby's development
CDC (US)	About 6 months	Introduce allergenic foods alongside other foods
ESPGHAN (Europe, 2017)	Not before 4 months (17 weeks), not later than 6 months (26 weeks)	About 6 months of exclusive or predominant breastfeeding is a "desirable goal"

So the honest answer is: aim for around 6 months, and never before 4 months. The window between 4 and 6 months is a conversation to have with your pediatrician or health visitor, especially for premature babies, for whom the NHS advises asking for individual advice.

The three readiness signs (all three, together)

The NHS lists three signs that, appearing together from around 6 months, show your baby is ready:

Sitting steady: your baby can stay in a sitting position and hold their head steady.
Eyes, hands and mouth working together: they can look at food, pick it up and put it in their mouth.
Swallowing: they swallow food rather than pushing it back out with the tongue.

The AAP adds a practical check: babies may be ready when they watch you eat, reach for your food and open their mouth when food comes their way.

Not readiness signs: chewing fists, wanting extra milk feeds and waking more at night. The NHS describes these as normal baby behaviours. A little extra milk often helps until the real signs appear.

Your first-weeks plan

This is a calm, flexible sequence built on NHS and AAP guidance. Your baby sets the pace.

Stage	What to offer	How much	Source
First days	One food, once a day, at a time that suits you both	Half a spoonful or less to start	NHS, AAP
First weeks	Vegetables that are not too sweet (broccoli, cauliflower, spinach) alongside other first foods	Increase gradually, guided by your baby's appetite	NHS
As soon as your baby manages	Mashed and lumpy textures plus soft finger foods	Keep offering lumps from around 6 to 7 months	NHS
7 to 9 months	Moving towards 3 meals a day	Wide variety for energy and iron	NHS
10 to 12 months	3 meals a day plus milk feeds	Bigger chunks of soft food, more finger foods	NHS

A few principles make the whole journey easier:

Milk stays the main food. The NHS and the AAP both remind that breast milk or first infant formula provides most energy and nutrients at first. Offer milk on demand.
Iron and zinc early. The AAP recommends including foods that provide iron and zinc, such as meat or iron-fortified cereals; the NHS lists meat, fish, eggs, beans and pulses from around 6 months.
One new food at a time. The CDC suggests single-ingredient foods at first and waiting 3 to 5 days between each new food, so you can spot a reaction.
No added salt or sugar. The NHS explains that salt is not good for a baby's kidneys and sugar can cause tooth decay; ESPGHAN says the same.
Never force. If your baby cries or turns away, the AAP advises not to make them eat; go back to milk for a while and try again later.

The free solids calendar turns this plan into a dated week-by-week schedule from your baby's birth date.

Purees, finger foods or both?

There is no single right method. The NHS says some parents spoon-feed, some prefer baby-led weaning with finger foods from the start, and many combine both. What matters is that your baby eats a wide variety of foods and moves on to lumpier textures in time. Whichever way you go, cut and cook food to a safe shape: the first foods size chart shows how for each age.

Allergens are first foods too

The CDC advises introducing potentially allergenic foods (egg, peanut as a thinned butter, wheat, fish and others) at the same time as other foods, and the NHS lists them as suitable from around 6 months, one at a time. Babies with severe eczema or an egg allergy need a plan with their doctor first. Read how to introduce allergens for the step-by-step.

Foods and drinks to hold back

Item	Guidance	Source
Cow's milk as a drink	Not before 12 months (fine in cooking from about 6 months)	NHS, CDC
Honey	Not before 1 year (risk of infant botulism)	NHS
Whole nuts	Not before 5 years (choking); ground or as a thin spread is fine	NHS
Fruit juice	Not before 12 months	AAP
Added salt, stock cubes, gravy	Avoid	NHS
Baby cereal in a bottle	Do not (choking risk) unless a doctor advises it for reflux	AAP

Safety at every meal

Sit your baby upright and strapped in a high chair, and stay with them for the whole meal.
Gagging is a normal reflex while learning; choking is silent. Learn the difference on our choking vs gagging page before the first meal.
A first aid course for babies is the single most useful hour you can spend before starting solids.

When to call a professional

Call 911 (US) or 999 (UK) if your baby cannot breathe, cough or cry, or shows signs of a severe allergic reaction such as swelling of the lips or tongue, breathing difficulty or sudden floppiness.
Call your pediatrician, GP or NHS 111 if stools become very loose, watery or full of mucus and stay that way (the AAP flags this), if a rash or vomiting follows a new food, or if your baby consistently refuses all solids for weeks.
Ask before starting if your baby was born prematurely, has severe eczema, a known food allergy, or a medical condition affecting swallowing.

Questions parents ask

Can I start solids at 4 months?

ESPGHAN says solids should not be introduced before 4 months (17 weeks), while WHO, the NHS and the AAP recommend waiting until about 6 months. If you are thinking of starting before 6 months, or your baby was born prematurely, talk to your pediatrician or health visitor first.

Will starting solids help my baby sleep through the night?

No. The NHS states that starting solid foods will not make your baby more likely to sleep through the night, and that night waking and wanting extra feeds are normal baby behaviours, not readiness signs.

How much food does my baby need at first?

Very little. The NHS suggests a small amount once a day to begin with, and the AAP suggests starting with half a spoonful or less. Breast milk or formula stays the main source of nutrition for now.

Do I need special equipment?

A high chair where your baby sits upright and strapped in, an open or free-flow cup for sips of water, and soft spoons, according to the NHS list. Everything else is optional.
