If you are anything like I was, you will wonder about weaning long before your baby is ready. One day your little one is happily having milk, and the next they are staring at your toast like it is the most interesting thing in the world. I remember thinking, does this mean we should start? Is it too early?
I am Daisy, and I have sat at that messy kitchen table too, spoon in hand, unsure if I was doing the right thing. Weaning is not a race. What helped me most was learning the real signs of readiness, so that is what I will share here.
Quick Answer
Most babies are ready to start weaning at around 6 months old. Weaning should never start before 4 months, which is 17 weeks, and starting earlier than around 6 months should only happen on professional advice from a doctor or health visitor.
Your baby is likely ready when they can do all three of these things: sit up with support and hold their head steady, reach for things and bring them to their mouth, and swallow food rather than pushing it straight back out with their tongue. If they cannot do all three yet, wait a little longer and try again in a week or two.
Breast milk or formula remains your baby’s main source of nutrition through the whole first year. First foods start small, just a few spoonfuls once a day. No added salt or sugar is needed for babies.
What Weaning Actually Means
Weaning means introducing solid foods alongside your baby’s usual milk. Solids complement milk at first, they do not replace it. In the first weeks your baby will probably eat very little. A lot will end up on the highchair and the floor, and that is normal. They are learning a new skill: moving food around in their mouth and swallowing something thicker than milk.
Keep it low pressure. Offer food when your baby is awake and not too tired, a little while after a milk feed. If they turn away or get upset, stop and try another day. If milk feeding itself has been tricky, my guide to a baby refusing the bottle may help you feel calmer first.
The Three Real Signs Your Baby Is Ready
Look for all three signs together, not just one on its own.
1. They can sit up with support and hold their head steady
Your baby does not need to sit completely alone, but in a highchair they should sit upright with support and keep their head steady. Sitting upright helps them swallow safely. If their head flops or they slump to one side, they are not quite ready yet, however keen they seem.
2. They can reach, grab, and bring things to their mouth
Can your baby pick up a toy and bring it to their mouth on purpose? This hand-to-mouth coordination shows they are developing the skills they need for soft finger foods. My little one practised for weeks on toys first, and that practice counted.
3. They have lost the tongue-thrust reflex
Young babies have a reflex that pushes anything solid straight back out with their tongue. It protects them when they are tiny, and it usually fades near 6 months. If a tiny amount of soft food comes straight back out again and again, your baby may not be ready yet. Waiting a week or two often makes a big difference.
Signs That Can Be Misleading
A few normal behaviours often get mistaken for readiness, but on their own they are not reliable signs:
- Watching you eat with great interest
- Seeming hungry, or wanting milk more often
- Waking more in the night
- Chewing their fists or mouthing everything
Watching parents eat is lovely, and a good reason to bring your baby to the table to join in socially. But interest alone does not mean their body is ready. Extra hunger is usually a growth spurt, a sign to offer more milk, not solids. Mouthing toys is normal exploration too, not the same as bringing food to the mouth.
Why Waiting Until Around 6 Months Matters
Around 6 months, most babies’ digestive systems, kidneys, and immune system are better able to cope with solid foods. Starting before 4 months, or 17 weeks, is never recommended.
If your baby was born early, or there are concerns about growth or reflux, your doctor may advise you differently. Earlier weaning should only happen on professional advice tailored to your baby. If you are unsure, a quick chat with your health visitor or doctor is always worth it.
How to Start, Simply and Calmly
- Choose a time when your baby is alert and you are not rushed.
- Seat your baby upright in a highchair, and always stay with them while they eat.
- Start with a few spoonfuls of a single soft food, once a day.
- Try soft cooked vegetables, soft fruit, or baby cereal mixed with their usual milk. Food should be soft enough to squash between your fingers.
- Let your baby touch the food and make a mess. Exploring is learning.
You can offer a spoon, soft finger foods, or a mix of both. Follow your baby’s lead and build up gradually. For a gentle structure, see my baby’s first foods week-by-week plan.
Keep breast milk or formula as the main drink through the first year. With meals, you can offer small sips of plain water in an open or free-flow cup. Babies do not need juice, sweet drinks, or added sugar.
Safety Rules I Never Skip
No honey before 12 months
Never give honey to a baby under 12 months, not even a taste, and not cooked into food. Honey can contain bacteria a young baby’s gut cannot handle safely. After the first birthday, honey is fine.
No added salt or sugar
Do not add salt to baby food, and be careful with salty adult foods like stock cubes, sauces, and processed meats. A baby’s kidneys cannot cope with much salt. Sugar is not needed either. Let fruit provide natural sweetness instead.
Stay close and keep food soft
Always supervise eating and keep your baby sitting upright. Cut round foods lengthways and cook hard vegetables until soft. Avoid hard, whole, or round items that are difficult for a baby to manage.
Introducing Allergens, Carefully
Once weaning is established, introduce common allergens one at a time, in small amounts. These include well-cooked egg and smooth peanut, such as peanut butter thinned with water or mixed into puree. Never give whole nuts to a young child.
One at a time, with a couple of days before another new allergen, makes it easier to spot if something does not agree with your baby. Start earlier in the day so you can watch them afterwards.
If your baby has eczema, or there is a strong family history of allergy, ask a doctor first. Introducing allergens is not a promise that allergies will be prevented.
What If My Baby Refuses, Gags, or Gets Constipated?
Refusing is normal. Some babies need to see and touch a food many times before tasting it. Keep offering without pressure, and remember milk still provides most of their nutrition.
Gagging is common too. It looks scary, with coughing and their tongue pushing forward, but it is a protective reflex that moves food away from the airway. Staying calm helps your baby stay calm.
Starting solids can also make poos firmer, and some babies get a little blocked up. My guide to baby constipation explains gentle everyday steps, and when to get advice.
Mistakes to Avoid
- Starting before 4 months, or just because your baby watches you eat.
- Treating one readiness sign as enough, instead of looking for all three together.
- Rushing portions. Solids start small, and milk stays the main nutrition for the first year.
- Adding salt, sugar, or honey. Honey must wait until after 12 months.
- Introducing several allergens on the same day.
- Forcing food when your baby turns away. Pressure usually makes refusing worse.
- Leaving your baby alone with food, or offering food lying down or sleepy.
- Comparing your baby to another baby. Readiness varies by a few weeks, and that is normal.
When to See a Doctor
Get medical advice promptly if you notice any of the following:
- Signs of an allergic reaction, such as swelling of the lips or face, difficulty breathing, widespread hives, or repeated vomiting after a new food. Difficulty breathing needs urgent, emergency help.
- Your baby regularly chokes, coughs a lot during feeds, or struggles to swallow.
- Your baby is not gaining weight as expected, is losing weight, or you worry about growth.
- Constipation is severe or lasting, or comes with a swollen tummy, blood in their poo, or pain.
- Your baby was born early, has eczema, or there is a family allergy history, and you need timing or allergen advice.
- You are thinking about starting weaning before around 6 months for any reason.
You know your baby best. If something feels wrong, even if it is not on this list, trust yourself and ask a doctor or health visitor.
Frequently Asked Questions
Can I start weaning at 4 or 5 months?
Never before 4 months, or 17 weeks. Most babies are not ready at 4 or 5 months, even if they seem interested. Wait until around 6 months and until your baby shows all three readiness signs. Earlier weaning should only happen on professional advice.
How much food should my baby eat at first?
Very little, and that is fine. A few spoonfuls once a day is a perfect start. Milk is still the main source of nutrition through the first year, so early solids are about learning and tasting, not filling up.
My baby pushes all the food back out. Should I keep trying?
If food comes straight back out every time, your baby has probably not lost the tongue-thrust reflex yet. Pause and try again in a week or two. Most babies get there in their own time, and waiting usually makes the next try more successful.
When can my baby have peanut and egg?
Once weaning is established, introduce well-cooked egg and smooth peanut one at a time, in small amounts. Never give whole nuts. If your baby has eczema or a family allergy history, ask a doctor first, and get urgent help for any difficulty breathing or swelling.
