Weaning a Baby: 6 Essential Tips for First-Time Parents

Weaning starts at around six months for a reason that often gets left out: that’s the point where a baby’s iron stores, built up before birth, start running low and milk alone no longer covers what they need. Understanding that changes what should go on the tray first and it’s the difference between weaning that supports a baby nutritionally and weaning that’s just spoon practice.

The six that follow are the ones that matter most in the first few months.

1. Wait for the readiness signs, then go slowly

Age is a guide, not the test. Three signs together indicate a baby is ready for solids: they can stay in a sitting position and hold their head steady, they can coordinate eyes, hands and mouth well enough to look at food, pick it up and bring it to themselves and they can swallow food rather than pushing it straight back out with their tongue.

Interest in what you’re eating doesn’t count on it’s own. Neither does waking more at night or chewing their fists, both of which are normal at four and five months and get misread as hunger for solids constantly.

Once you start, begin with a few teaspoons once a day and build gradually on quantity, frequency and texture. Breast milk or formula remains the main source of nutrition until twelve months, so early solids are exposure and practice, not replacement. Let the baby set the pace and stop when they show they’ve had enough.

2. Lead with iron and use foods that actually contain it

This is where standard first-food advice most often goes wrong. The foods that genuinely address the iron gap:

• Well-cooked meat and fish, pureed, minced or in soft strips, fully deboned. Red meat is the strongest option because haem iron, the form found in meat, absorbs far more readily than plant-based iron.
• Pulses — lentils, beans and chickpeas, cooked soft and mashed.
• Well-cooked eggs, using British Lion stamped eggs, which are safe even lightly cooked.
• Iron-fortified cereal, where fortified is the operative word.

Two foods that appear on iron lists constantly and shouldn’t: plain baby rice, which is not a meaningful iron source unless specifically fortified and mashed avocado, which is a good first food with almost no iron in it. Separately, rice drinks are not suitable for children under five at all, owing to inorganic arsenic content.

Vitamin C improves absorption of non-haem iron, so soft fruit or well-cooked pepper served alongside pulses does measurable work.

Pallor, unusual lethargy and irritability can indicate low iron. Raise it with your health visitor rather than adjusting the diet independently.

3. Leave out salt and sugar completely

An infant’s kidneys cannot process much salt and there is no nutritional case for added sugar at this stage. Food that tastes of nothing to an adult palate tastes of a great deal to one that has only ever had milk.

The practical difficulty is hidden salt rather than the salt cellar: stock cubes, gravy, bacon, cheese, bread and shop-bought sauces carry more than most parents expect, which is why cooking a portion out before seasoning the family meal is the usual approach. Early exposure to salt and sugar establishes preferences that are genuinely difficult to shift later, so this is one of the few areas where strictness at the start saves work down the line.

4. Progress the texture and learn the difference between gagging and choking

Once purees are comfortable, move to mashed food and finger foods: soft cooked vegetables and fruit, toast strips, pasta spirals, finely minced meat. Increase the size and variety of pieces as chewing develops. For practical preparation, there’s a useful guide to cooking vegetables soft enough for little hands that breaks it down by stage.

Then the distinction every parent needs before it happens rather than during:

Gagging is loud. Choking is silent.

Gagging presents as coughing, spluttering, retching, watering eyes, a red face and food being pushed forward out of the mouth. It is a protective reflex working exactly as intended while a baby learns where the back of their mouth is and it does not require intervention. Staying calm matters here, because a strong reaction from you teaches a baby to be frightened of food.

Choking is quiet. A choking infant cannot cough, cry or make sound, may turn blue and cannot clear the obstruction. This is an emergency: call 999 and begin infant choking first aid immediately. Read the NHS guidance before you need it and if you have not done an infant first aid course, this is the reason to.

Risk reduction is straightforward. Quarter grapes and cherry tomatoes lengthways, cook hard fruit and vegetables such as carrot and apple until soft, remove stones, pips and bones, avoid whole nuts entirely (nut butters and ground nuts are fine) and stay with your baby throughout every meal with them seated upright.

5. Introduce allergens early, one at a time

The guidance here reversed some years ago and a great deal of older advice is still circulating. Current recommendation is to introduce the common allergens from around six months rather than delaying them, because delayed introduction appears to increase the risk of allergy rather than reduce it.

The method matters as much as the timing:

• One allergen at a time, in a small amount.
• Earlier in the day rather than near bedtime, so there is time to observe.
• Roughly three days before introducing the next, so any reaction can be attributed accurately.

The main allergens are cow’s milk in food, eggs, peanuts and tree nuts (ground or as butter, never whole), seeds, soya, wheat, fish and shellfish.

Watch for signs of an allergic reaction: rash or hives, vomiting, diarrhoea, swelling of the face or lips or any breathing difficulty. First reactions are rarely severe, but facial swelling or breathing trouble warrants calling 999 without delay. Anything milder or anything that simply concerns you, goes to your health visitor. Foster carers have an additional route here and Fostering People can direct you to your social worker for guidance on feeding, allergies and related questions.

6. Know what to avoid before twelve months and keep mealtimes calm

The short list, which is easy to miss because much of it is ordinary household food:

• Honey — not before twelve months, due to the risk of infant botulism.
• Whole nuts — a choking hazard; ground or as butter is fine.
• Cow’s milk as a main drink — acceptable in cooking from six months, but breast milk or formula remains the main drink until one.
• Raw or partially cooked eggs without the British Lion mark.
• Low-fat and “diet” foods — infants need the fat.
• Shark, swordfish and marlin, owing to mercury content.

Beyond the food itself, the atmosphere at the table does more long-term work than any individual meal. Mess is part of the process and so is touching, squashing and dropping food, all of which is how an infant establishes that something is safe to eat. Babies allowed to explore tend to accept a wider range later.

Weaning has a way of turning into a daily assessment of your parenting and tense mealtimes are one of the more reliable routes to fussy eating. There will be days when a baby refuses everything offered. That is a normal day, not a setback. Offer, stay unbothered and let it go.
