Starting solids at 6 months: a step-by-step guide for the first weeks

Feeding · Updated July 2026 · All articles

The first taste of real food is a milestone that can feel both exciting and nerve-wracking. There is advice everywhere, and much of it contradicts itself. This guide cuts through the noise with a simple, step-by-step plan grounded in NHS and WHO guidance. If your baby is around 6 months old and showing the right signs, this is everything you need to begin with confidence.

The three signs of readiness (and what does not count)

The NHS, WHO, and most health authorities around the world now recommend that babies start solid foods at around 6 months of age. But age alone is not the only guide. Three physical signs need to be present before you begin:

1. Sitting upright with minimal support. Your baby should be able to hold their body upright in a high chair or on your lap, keeping their head and neck steady. A baby who slumps to one side or whose head bobs has not yet developed the trunk and neck control needed to manage food safely.
2. Strong head and neck control. Your baby's head should be steady when they sit or are held upright. They should be able to turn their head to indicate they do not want any more food, which is an essential communication signal during mealtimes.
3. Loss of the tongue-thrust reflex. Young babies automatically push anything placed in their mouth outward with their tongue. This reflex protects them from choking before they are ready for solids. When it fades, around 6 months for most babies, they can move food toward the back of the mouth to swallow.

There are signs that are often cited but that do not, on their own, signal readiness: watching you eat with interest, reaching toward your plate, or putting toys and hands in their mouth. These are normal infant behaviours at almost any age. All three physical signs above should be present before you introduce solids.

If your baby was born prematurely, calculate readiness from their corrected age rather than their birth age, and check with your health visitor or paediatrician before starting.

Why 6 months matters: gut readiness and iron timing

Starting solids before 4 months is not recommended for two important reasons. First, the digestive system is not mature enough: the gut lining is still developing, and introducing food too early increases the risk of digestive problems and may raise the likelihood of food allergy. Second, the immune system is still learning to tolerate new antigens, and premature food introduction disrupts that process.

The 6-month window is not arbitrary. It aligns with two significant developmental shifts. The physical readiness signs described above typically coincide with maturation of the gut and immune system. And critically, a baby's iron stores from birth begin to run low at around 6 months. Breast milk and formula do not contain enough iron to keep up with a growing baby's needs beyond this point. Solids, particularly iron-rich ones, become a necessary complement to milk from around 6 months.

Starting later than 7 months is also associated with difficulty accepting new textures later on. The window between 6 and 9 months is when babies are most receptive to learning to manage different food textures. This does not mean there is cause for anxiety if you start at 6.5 or 7 months, but it does mean that deliberately waiting past 7 months is not recommended.

The first two to four weeks: once a day is enough

Many parents worry that their baby is not eating enough when they begin weaning. The reality is that the amount eaten in the first few weeks does not matter at all. The goal of the first two to four weeks of weaning is exploration and experience, not nutrition. Milk, whether breast milk or formula, remains your baby's primary source of nutrition throughout the entire first year.

In the first weeks, offer solids once a day. Choose a time when your baby is alert and content, not exhausted or ravenously hungry. Just before a milk feed, or about an hour after, tends to work well. You are looking for a relaxed, curious mood rather than frantic hunger.

Keep the amounts small: a teaspoon or two is plenty to start. Your baby may eat nothing at first, may pull a face, may spit everything out. All of this is normal. The act of placing food in the mouth, tasting it, and learning to move it around is the achievement, regardless of whether any is actually swallowed.

After two to four weeks, you can move to two meals a day, and by 9 months most babies are ready for three meals alongside their milk feeds. Do not rush this progression. Follow your baby's cues.

What to offer first: iron-rich foods are the priority

Most parents default to offering sweet vegetable and fruit purees first: sweet potato, butternut squash, pear, apple. These are easy to prepare and babies tend to accept them readily. But this approach misses the most important nutritional need at 6 months: iron.

Iron-rich foods should feature from the very first meal, not after a few weeks of vegetables. The NHS and CDC are both clear on this. Good iron-rich first foods include:

• Well-cooked meat pureed or finely minced: chicken, beef, lamb, pork
• Well-cooked fish, such as salmon or trout, flaked finely
• Mashed cooked lentils or split peas (red lentil dal with no added salt or spices is a classic)
• Mashed cooked egg yolk (the yolk is iron-rich; hard-cook both the white and yolk fully for babies)
• Iron-fortified baby rice cereal or oat porridge
• Mashed cooked chickpeas or kidney beans

You do not need to offer only iron-rich food at every meal. But aiming for at least one iron-rich food per day from the start gives your baby's nutrition the foundation it needs. Pairing plant-based iron sources with a small amount of vitamin C (a squeeze of orange juice stirred into lentil puree, or soft-cooked tomato) helps the body absorb non-haem iron more efficiently.

Texture: puree or soft finger food, not watery

There is no single correct texture to begin with. You can start with smooth puree offered on a spoon, with soft mashed food, with soft finger foods, or with a combination. What matters is that the texture is appropriate for your baby to manage safely.

A few texture principles for the early weeks:

• Purees should be thick and smooth, not watery. A runny consistency is harder to manage and does not help the baby develop swallowing skills. Aim for the consistency of thick yoghurt or soft hummus.
• Soft mashed food should be lump-free at first but need not be perfectly smooth. A slightly textured mash is fine from around 6 to 7 months.
• Finger foods should be very soft and large enough for the baby to grip in their fist with a portion sticking out, roughly the length and width of an adult finger. A stick of well-steamed carrot, a strip of ripe avocado, or a finger of soft-cooked broccoli floret all work well.

Do not add water or excess formula to thin purees down. If a food is too thick to serve, cook it a little longer, or blend it with a small amount of your baby's usual milk rather than water, which adds familiar flavour and improves iron absorption from plant foods.

Gagging versus choking: knowing the difference

Gagging is one of the most alarming things parents witness in the first weeks of weaning, and it is one of the most misunderstood. Here is the key distinction:

Gagging is normal and protective. You will see your baby's face scrunch, their mouth open wide, and sometimes a retching or coughing sound. They may go a little red. Gagging happens when food reaches the back of the mouth before the baby has fully moved it into position to swallow. The reflex pushes the food forward, protecting the airway. Stay calm. Do not put your finger in to sweep the food out. Let your baby manage it. Gagging reduces as oral motor skills develop over the first weeks and months.

Choking is different and requires immediate action. A choking baby goes silent or makes very little sound, cannot cough effectively, may turn red or blue, and appears distressed. This is a partial or complete airway obstruction. Every caregiver should know the infant choking first-aid response before starting solids: five back blows between the shoulder blades followed by five chest thrusts, and calling emergency services if the obstruction does not clear.

Minimise choking risk by always supervising meals, ensuring your baby is upright, and avoiding hard, round, or coin-shaped foods. Safe shapes are long, soft strips that a baby can hold in their fist. Grapes, blueberries, cherry tomatoes, whole nuts, raw hard vegetables, and large globs of nut butter are not appropriate for babies under 1.

Water and drinks: the open cup

From 6 months, offer small sips of cooled boiled water with meals from an open cup or a free-flow sippy cup. An open cup (such as a small shot glass or a Doidy cup) is actually preferable to a lidded sippy cup because it teaches the baby to sip rather than suck, which supports speech development and dental health.

The amount of water needed at this age is small. Milk feeds provide most of the fluid your baby needs. A few sips with meals is plenty. Do not replace milk feeds with water.

Fruit juice, squash, and flavoured drinks are not appropriate for babies under 12 months. Even pure fruit juice is high in sugar and provides no nutritional benefit that whole fruit does not offer.

Foods to avoid under 12 months

A short checklist of what to leave out:

• Honey: never before 12 months, due to the risk of infant botulism. This includes raw honey, cooked honey, and foods made with honey such as honey-flavoured cereals.
• Added salt: a baby's kidneys cannot process excess sodium. Do not add salt to food, and check labels on any commercial products. Many adult foods, including cheese, bread, and stock cubes, are high in salt.
• Added sugar: avoid foods with sugar added. This builds a preference for sweetness that can be difficult to shift later.
• Whole nuts: a choking hazard for all children under 5. Ground nut butter spread thinly on toast is fine from 6 months and is an excellent way to introduce peanut.
• Cows milk as a main drink: full-fat dairy as food (yoghurt, cheese, milk used in cooking) is fine from 6 months. But cows milk should not replace breast milk or formula as the main drink before 12 months, as it does not meet a baby's nutritional needs in that role.
• Shark, swordfish, and marlin: these contain high levels of mercury. Oily fish such as salmon, mackerel, and sardines are fine and valuable from 6 months.

When your baby refuses

It is genuinely common for babies to refuse solid food for the first few attempts, or even for the first few weeks. This is not a problem. Here is what actually helps:

• Keep offering calmly, without pressure. The more relaxed the mealtime feels, the more likely your baby is to explore food on their own terms.
• Try different times of day. Some babies are most receptive mid-morning; others do better at lunchtime. Avoid offering solids when your baby is very hungry (they want milk, not experiments) or overtired.
• Let your baby touch and explore food before eating it. Babies learn through all their senses. Squeezing, smearing, and throwing is all part of the process.
• Eat with your baby. Watching a caregiver eat the same food is one of the most powerful ways to encourage a baby to try it.
• Persistent, complete refusal over several weeks, or any concerns about weight gain, are worth raising with your health visitor.

Frequently asked questions

How do I know my baby is ready for solids?

There are three physical signs to look for: your baby can sit upright and hold their head steady without much support; they have good control of their head and neck; and they have lost the tongue-thrust reflex that pushes food out of the mouth. All three should be present. Watching food or putting things in their mouth is normal baby behaviour at any age and is not a readiness sign on its own.

Is 6 months too late to start solids?

No. The NHS and WHO recommend introducing solids at around 6 months. Starting before 4 months is not recommended as the gut is not ready. Anywhere in the 6-month window is appropriate once the three readiness signs are present. If you have concerns about timing, speak to your health visitor.

How much should a baby eat in the first weeks of weaning?

Very little, and that is completely expected. The goal in the first two to four weeks is for your baby to experience new tastes and textures, not to eat a set amount. Milk remains the main source of nutrition throughout the first year. Start with one small meal a day, and let your baby guide how much they take.

What should I offer as a first food?

Iron-rich foods should feature from day one, because a baby's iron stores from birth begin to run low at around 6 months and milk alone cannot replenish them. Good choices include well-cooked, pureed or mashed meat, mashed cooked lentils, mashed egg yolk, or iron-fortified baby cereal. Pair these alongside soft vegetables and fruit.

My baby keeps gagging. Should I stop?

Gagging is a normal protective reflex, not choking. It looks alarming but it is the baby's airway protecting itself by pushing food forward. Most babies gag frequently in the early weeks of weaning. Stay calm, let them work through it, and do not rush in to remove food. Choking, by contrast, is silent and requires immediate action. Learning the difference, and basic infant first aid, is worthwhile before you begin.

What if my baby refuses everything I offer?

Refusal is very common at the start. Babies may need to see and smell a new food many times before accepting it. Keep offering calmly, without pressure or coaxing. Try different times of day, when your baby is alert but not overtired or ravenously hungry. It can take ten or more exposures before a baby accepts a new food. If refusal continues across many weeks or you have concerns about growth, speak to your health visitor.
