Weaning & Starting Solids

When to Start: Readiness Over the Calendar

The NHS recommends introducing solid foods at around 6 months, and not before 17 weeks (four months). This guidance is based on evidence that the gut, kidneys, and neuromuscular system are not sufficiently developed before this point to process solid food safely. Starting too early is associated with increased risk of choking, gut discomfort, and later food allergies.

The operative word in the NHS guidance is "around" — babies are ready when their development indicates it, not on a fixed date. Age alone is not a reliable signal. The three signs of readiness should all be present before you begin.

The three signs of readiness

• Sitting with minimal support and holding their head steady — this indicates the postural control needed to eat safely. A baby who slumps forward in their highchair is not ready.
• Coordinated hand-to-mouth movement — the ability to pick something up and bring it to their mouth, which is the motor foundation for self-feeding.
• Loss of the tongue-thrust reflex — the automatic pushing-out of anything placed on the tongue. If food is consistently expelled, the reflex is still active and the baby is not yet ready.

First Foods: What to Offer and When

The goal in the first weeks of weaning is exploration and exposure, not nutrition. Your baby's nutritional needs are still being met entirely by milk — breast or formula — and this remains the case for several months. Pressure to achieve volume at this stage is counterproductive; the baby's job is to experience new flavours, textures, and the process of eating.

Start with single-ingredient foods with distinct flavours. The instinct to begin with very bland options — plain rice, unseasoned potato — misses an opportunity. Research from the SACN (Scientific Advisory Committee on Nutrition) and multiple weaning studies suggests that early exposure to a wide variety of flavours, including bitter and savoury ones, significantly reduces the likelihood of fussy eating later.

Good first foods

• Vegetables — cooked and soft: broccoli, cauliflower, sweet potato, carrot, parsnip, courgette, pea. Starting with vegetables before fruit builds acceptance of savoury flavours before sweetness is established as the norm.
• Fruits — banana, avocado, soft cooked apple or pear. Offer alongside rather than instead of vegetables.
• Protein — soft-cooked egg (well done, not runny until 12 months unless pasteurised), cooked lentils and beans, soft flakes of white fish or oily fish, well-cooked and shredded chicken or meat.
• Starchy foods — soft-cooked pasta, rice, bread, oats, polenta. These can be introduced from the beginning and are useful vehicles for other flavours.

Foods to avoid in the first year

• Honey — risk of infant botulism. Not before 12 months under any circumstances.
• Whole cow's milk as a main drink — can be used in cooking from 6 months, but not as a replacement for breast milk or formula until 12 months.
• Salt — babies' kidneys cannot process adult amounts of salt. Avoid adding salt to food; check labels on any packaged foods used.
• Added sugar — not needed and establishes a preference for sweetness that complicates broader food acceptance.
• Shark, swordfish, and marlin — high mercury content. Other oily fish (salmon, mackerel, sardines) are strongly encouraged for omega-3 content.
• Whole nuts — choking hazard until 5 years. Ground or nut butters are fine from 6 months (and actively encouraged for allergen introduction).
• Raw or runny eggs — until 12 months, unless British Lion stamped (pasteurised).

Purees, Baby-Led Weaning, or Both?

The weaning approach debate — spoon-fed purees versus baby-led weaning (BLW) — generates considerable heat in parenting communities, but the honest answer is that the evidence supports a combined approach for most families, and the differences between the methods are smaller than advocates on either side suggest.

Traditional spoon-feeding and purees

Purees and spoon-feeding have a long track record and are the approach most familiar to grandparents offering to help. They allow precise portion control, easier monitoring of intake, and can be easier to manage when family schedules are pressured. The main limitation is that purees alone, if maintained too long, can delay texture acceptance — babies who are not introduced to lumpier foods by around 9 months have a significantly higher risk of feeding difficulties later. Progression through textures is essential.

Baby-led weaning (BLW)

BLW involves offering soft finger foods from the start and allowing the baby to feed themselves, bypassing purees entirely. Benefits include better self-regulation of intake, earlier development of chewing skills, exposure to family foods and mealtimes, and — in some research — lower rates of picky eating. The main concerns are around nutritional adequacy (particularly iron) and anxiety about choking, though research suggests BLW is safe for babies who meet the readiness criteria and are offered appropriately prepared foods.

A combined approach

Most families naturally combine methods — offering some spoon-fed foods and some finger foods from early on. This is entirely sensible. The practical principles that matter most are: progress textures consistently, always offer finger foods alongside spoon-fed ones, eat together as a family where possible, and do not extend the puree phase beyond necessity.

Introducing Allergens

The guidance on allergen introduction has changed significantly in the past decade, and many parents are working from outdated information. Current NHS and SACN guidance is clear: the top allergens should be introduced early — from around 6 months — and not avoided. Delayed introduction of allergens is associated with increased risk of allergy development, not decreased.

The eight most common allergens requiring careful introduction are: cow's milk (in solid food from 6 months), eggs, peanuts, tree nuts, sesame, fish, shellfish, and wheat/gluten. Each should be introduced individually, in a small amount, on a day when your baby is well, ideally in the morning so you can monitor for any reaction during the day.

How to introduce each major allergen

• Peanuts — smooth peanut butter or peanut flour mixed into a soft food (not whole nuts — choking hazard). Start with a very small amount on the tip of a spoon.
• Egg — well-cooked scrambled egg or hard-boiled egg, mashed. Introduce egg white and egg yolk together.
• Wheat — soft bread, pasta, or porridge oats (oats contain gluten for most purposes). Bread soldiers with soft toppings are a practical option.
• Cow's milk protein — full-fat yoghurt or cheese are the easiest vehicles. Remember that whole cow's milk as a main drink is not introduced until 12 months.
• Fish — soft, well-cooked white fish or salmon, carefully checked for bones. Tinned salmon or sardines in spring water (not brine) are convenient options.
• Sesame — a small amount of tahini (sesame seed paste) mixed into food.
• Tree nuts — smooth almond, cashew, or hazelnut butter mixed into yoghurt or porridge.

Signs of allergic reaction to watch for

Most allergic reactions to food occur within 2 hours of ingestion. Mild reactions include hives, redness or swelling around the mouth, and mild itching. These can be monitored and discussed with your GP. Severe reactions (anaphylaxis) include difficulty breathing, severe swelling of the lips, tongue or throat, loss of consciousness, or sudden collapse — these require an immediate 999 call. Mild reactions to a first introduction do not prevent re-introduction; seek medical advice about how to proceed.

Managing Milk Feeds During Weaning

One of the most common weaning mistakes is reducing milk too quickly. In the first months of weaning, milk — breast or formula — remains the primary source of nutrition. Food is supplementary, exploratory, and developmental. Reducing milk feeds significantly before 9 months risks nutritional shortfall.

A useful framework: for the first month or two of weaning, offer milk feeds first and food approximately 30–60 minutes later. This ensures the baby is not so hungry that frustration interferes with food exploration, but not so full that food is irrelevant. From around 9 months, the balance begins to shift — more structured mealtimes, food offering more nutritional significance — but milk remains important until 12 months.

At 12 months, breast milk can continue for as long as mother and baby wish. Formula is no longer nutritionally necessary once a varied diet and cow's milk are established, though the transition can be gradual rather than abrupt.

Gagging, Choking, and the Difference Between Them

Fear of choking is one of the most significant barriers to relaxed, effective weaning — and it is a fear that is often not addressed clearly by health professionals or weaning guides. Understanding the physiological difference between gagging and choking is genuinely transformative.

Gagging is a protective reflex that moves food forward in the mouth when it reaches the back of the throat before the baby is ready to swallow it. In babies, the gag reflex is triggered much further forward on the tongue than in adults — meaning babies gag more frequently and more dramatically than we would. Gagging is loud, involves visible retching, and often makes the baby's eyes water. It looks alarming. It is safe. It is the system working correctly.

Choking is a partial or complete obstruction of the airway. It is silent — a choking baby cannot cough, cry, or make noise — because air is not moving. A baby who is making noise, however distressing, is not choking. A baby who suddenly goes silent, turns red or blue, and cannot cough or cry needs immediate intervention.

Foods that pose a genuine choking risk

• Whole grapes, cherry tomatoes, blueberries — always halve or quarter
• Whole nuts — grind or use as nut butter until 5 years
• Raw carrot, raw apple — cook or grate for under-12-months
• Whole sausages and round-cut hot dogs — slice lengthways
• Thick, sticky foods like whole peanut butter on a spoon — mix into another food
• Popcorn — avoid until at least 5 years

Fussy Eating: What Is Normal and How to Respond

Food refusal is one of the most emotionally loaded aspects of weaning. It feels personal. It can trigger anxiety about nutrition. It can make mealtimes miserable for everyone. Understanding the neuroscience of food acceptance makes it significantly less distressing.

Food neophobia — fear of new foods — is a normal developmental phenomenon that typically intensifies between 18 months and 3 years. It is an evolutionary protective mechanism: toddlers, who are becoming mobile and independent, need to be cautious about unfamiliar foods that could be poisonous. The brain treats novelty as potential danger. This is not stubbornness; it is neurologically normal behaviour.

The research on repeated exposure

Food acceptance research consistently finds that a new food needs to be offered between 10 and 15 times before many children will eat it. This is not 10 attempts over two weeks — it is 10 neutral, low-pressure exposures over time. Each exposure familiarises the brain with the food's appearance, smell, and texture. The key word is neutral: pressure, bribery, and coercion all increase food aversion, not decrease it. An untouched piece of broccoli on the plate is still an exposure. A lick counts. A bite that gets spat out counts.

The principles of a positive mealtime environment

• Eat together whenever possible — children learn from watching others eat. A parent who eats the same food without comment is the most effective fussy-eating intervention available.
• Division of responsibility — you decide what is offered, when, and where. The child decides whether and how much to eat. Do not negotiate over the menu or coerce eating.
• Never use food as reward or punishment — "eat your peas to get pudding" increases pea aversion and pudding desire simultaneously.
• Keep rejected foods in rotation — removing a food because it was rejected removes all future opportunities for acceptance.
• Do not make a separate meal — always include at least one accepted food alongside new ones, but do not routinely prepare an alternative if the main meal is rejected.
