Quick Answer

Most babies are ready for solid foods around 6 months — when they can sit with support, hold their head steady, and show interest in food. Start with iron-rich foods, introduce common allergens like peanut and egg early and one at a time, and keep breast milk or formula as your baby's main source of nutrition through the first year.

Based on AAP infant-nutrition and allergy-prevention guidance.

Starting solids is a fun milestone — and a common source of questions. The goal in the first year isn't to fill your baby up, but to practice: exploring flavors and textures while milk still does the heavy lifting.

Signs your baby is ready for solids

Around 6 months, most babies show the signs that they're ready:

  • They can sit up with support and hold their head steady.
  • They've lost the reflex that pushes food out of their mouth.
  • They watch you eat with interest and reach for food.

Age is a guide, not a rule — readiness is about development. If you're unsure, we'll check at your baby's well-visit.

First foods: where to start

Iron is the priority. Babies are born with iron stores that begin to run low around 6 months, so first foods should help replenish them: iron-fortified infant cereal, pureed or well-cooked meats, lentils, and beans. From there, add a rainbow of vegetables and fruits.

There's no medical reason to start with bland rice cereal specifically, and no need to introduce foods in a strict order. Single-ingredient foods simply make it easier to spot any reaction.

Introducing allergens safely

Guidance has changed: for most babies, introducing common allergens early — around 6 months, once solids are underway — may actually help prevent food allergies. Offer them one at a time, a few days apart, at home earlier in the day so you can watch for a reaction.

Common allergens include peanut (as a thinned peanut-butter puree, never whole nuts), egg, dairy, wheat, soy, fish, and shellfish.

Call 911 for signs of a severe reaction

Trouble breathing, swelling of the lips or face, repeated vomiting, or widespread hives after a food. If your baby has severe eczema or an existing food allergy, talk with us before introducing allergens.

Foods to avoid in the first year

A few foods aren't safe yet:

  • Honey — risk of infant botulism before age 1.
  • Choking hazards — whole nuts, whole grapes, popcorn, hard raw vegetables, chunks of hot dog.
  • Cow's milk as a main drink — wait until 12 months (small amounts in food are fine).
  • Added salt, sugar, and juice — not needed and best limited.

Making mealtimes positive

Follow your baby's cues, let them get messy, and don't force bites — early meals are about curiosity, not calories. Eating together and offering a variety of family foods (safely prepared) sets the stage for a healthy eater later on.

Frequently asked questions

Answers to the questions Calabasas parents ask us most.

When should my baby start solid foods?
Around 6 months, when your baby can sit with support, hold their head steady, and shows interest in food. Talk with us if you're considering starting earlier.
Should I start with rice cereal?
Not necessarily. What matters is offering iron-rich foods — iron-fortified cereal, pureed meats, or beans. There's no need to begin with rice cereal specifically.
How do I introduce peanuts safely?
Offer a small amount of smooth peanut butter thinned with water or mixed into a familiar food (never whole nuts), one time earlier in the day, and watch for any reaction. If your baby has severe eczema or egg allergy, check with us first.
Do I still breastfeed or give formula after starting solids?
Yes. Through the first year, breast milk or formula remains your baby's main source of nutrition — solids are practice and added nutrients, not a replacement.
What foods are choking hazards for babies?
Whole nuts, whole grapes, popcorn, hard raw vegetables, chunks of hot dog, and sticky globs of nut butter. Cut foods small and soft, and always supervise meals.
