When Can Babies Start Solid Foods?

The AAP recommends providing your baby only breast milk for approximately six months after birth, and then supports continued breastfeeding alongside introductory foods, for two years or beyond if you and your child want to. That is the recommendation, and it is the answer to when.

Alongside it the AAP lists readiness signs, and those are a separate thing from the date. Can your baby hold their head up and sit with good head control in a feeding seat? Do they open their mouth when food comes their way, watch you eat, reach for your food? Can they move food from a spoon to the back of the mouth and swallow it, rather than pushing it back out onto their chin?

One item in that list is worth reading carefully, because it is the one that gets quoted on its own. The AAP asks whether your baby is big enough, and says that generally, when infants double their birth weight, typically at about four months, and weigh about thirteen pounds or more, they may be ready. That is a floor inside a readiness checklist. It sits under a recommendation of approximately six months, and it is not an instruction to start at four.

This is the sentence most worth carrying away from the AAP's page, because it reverses what a great many parents were told: there is no evidence that waiting to introduce baby-safe soft foods, such as eggs, dairy, soy, peanut products or fish, beyond four to six months of age prevents food allergy.

There is one important exception attached to it. Testing for peanut allergy is recommended for babies with severe eczema, egg allergy, or both, and the AAP's advice for those babies is to check with your doctor about how and when to give peanut products. If that describes your baby, this is a conversation to have before the first spoonful rather than after.

The mechanics for everyone else are unchanged: one single-ingredient new food at a time, from any food group, every three to five days, watching for a reaction between them.

The other widely repeated rule is that vegetables must come before fruit or your baby will hold out for sweetness forever. The AAP addresses it directly and briefly: there is no evidence that your baby will develop a dislike for vegetables if fruit is given first.

What the AAP does ask you to prioritise is different and less discussed. Include foods that provide iron and zinc, because those are the nutrients a six-month-old's stores are running down, and the order of fruit and vegetables is not what determines the diet a year from now.

Parents spend a lot of energy on this decision, so it is worth knowing that the AAP's own guidance does not stage it as a contest. It does not name baby-led weaning as one approach and purees as another. What it says instead is that your baby's first foods are your choice, that making your own and buying premade are both fine, and that foods should be soft or pureed to prevent choking.

So the constraint the AAP actually sets is about texture and safety, not about who holds the spoon. Both methods can meet it and both can fail it. That reframing is more useful than a verdict, because it tells you what to check on any given plate.

One specific instruction sits alongside it: do not put baby cereal in a bottle. The AAP's reason is choking, plus the amount a baby ends up taking. If reflux has been raised with you, cereal in a bottle is something a doctor may suggest, and that is a decision to take with them rather than from an article.

Soft or pureed is the rule at the start, and choking is the reason for it. The rules that follow it run for years rather than months: a size limit on everything you cut, and a specific list of foods that stays off the menu until four years of age. Our guide to choking hazards and safe first foods covers both, along with which foods are allowed back once they are cut differently.

Start with half a spoonful or less, and expect confusion rather than enthusiasm. A wrinkled nose, food rolled around the mouth and then rejected, and most of the first few feedings ending up on the face and the bib are all the normal version of this.

A practical order helps: a little breast milk or formula first, then the half-spoonfuls, then more milk to finish. A very hungry baby has no patience for a new skill, and this is a new skill rather than a meal. At this stage almost all of the nutrition is still coming from milk.

If your baby cries or turns away, stop. Go back to milk for a while and try again another day, or in a week or two. Pushing turns a slow start into a fight, and the AAP's advice here is simply not to make them eat.

Two conversations belong with your doctor rather than with a schedule. The first is peanut, if your baby has severe eczema or a known egg allergy, and it is worth having early. The second is vitamin D and iron supplementation during the first year, which the AAP explicitly says to check on.

Beyond that, raise it if your baby consistently cannot move food to the back of the mouth and swallow well past six months, if solids are refused entirely over weeks rather than days, or if a food produces a reaction. A reaction with any breathing difficulty is an emergency and not a checkup question.
