Even though a baby’s diet changes a lot during the first year, there are some rules that are fairly consistent. The American Academy of Pediatrics recommends breastfeeding as the only source of food for at least six months, and that parents with a history of food allergies should avoid common food allergens such as peanuts and dairy. (Consult with a doctor as to when these foods should be introduced into your baby’s diet.)

Babies should be given a mix of fruits, vegetables, and proteins in order to provide a diverse nutritional profile, and they should be given a variety of foods to help prevent picky eating in the future. Though parents can’t be in complete control of all aspects of their baby’s health, they can still set a strong nutritional foundation.

Here’s a list of some of the healthiest and unhealthiest foods for your baby, according to various pediatricians and nutritionists.
