When should I start solid foods?

The right age

The World Health Organization recommends feeding only breast milk for about the first 6 months, then adding solids at 6 months while continuing to breastfeed. The American Academy of Pediatrics also recommends starting solids around 6 months and not before 4 months.

Starting before 4 months is linked to faster weight gain and added fat, and your baby is usually not yet physically ready. Age alone is not the trigger, though; watch for the readiness signs below.

Breast milk or formula stays your baby's main source of nutrition through the first year. Early solids are practice and added nutrition, not a replacement for milk feeds.

Readiness signs to look for

Your baby is likely ready when several of these line up, which for most babies happens around 6 months.

• Good head and neck control and can sit upright with support in a high chair.
• Has lost the tongue-thrust reflex, so food is not automatically pushed back out of the mouth.
• Can move food from a spoon to the back of the mouth and swallow, rather than dribbling most of it out.
• Shows interest in food by watching you eat, reaching for food, and opening their mouth.
• Is big enough, generally having about doubled birth weight and weighing roughly 13 pounds or more.

Start with iron-rich foods

Babies are born with iron stores and get iron from breast milk and formula, but those stores fall and by around 6 months babies need iron from food. Low iron at this age is a real concern, which is why first foods should be chosen for iron.

Good iron-rich starters include iron-fortified infant cereal and pureed meats such as beef, poultry, or fatty fish. Beans, lentils, and dark leafy greens add iron too.

Pairing iron-rich foods with vitamin C foods, such as a little pureed fruit, helps your baby absorb the iron. Anemia screening is commonly done around 12 months.

Can I start solids at 4 months?

Most babies should start around 6 months, and solids should not be introduced before 4 months. A few babies show clear readiness between 4 and 6 months, but the full set of signs, including sitting with support, losing the tongue-thrust reflex, and moving food to the back of the mouth, usually lines up around 6 months. Talk with your pediatrician before starting earlier than 6 months.

What should a baby's first food be?

Choose iron-rich foods first, because iron stores run low around 6 months. Iron-fortified infant cereal and pureed meats such as beef, poultry, or fatty fish are good starters, along with beans, lentils, and dark leafy greens. There is no medical reason it must be rice cereal specifically. Pairing iron foods with a vitamin C food helps absorption.

How do I know my baby is ready for solids?

Look for several signs together: good head and neck control, the ability to sit upright with support, loss of the tongue-thrust reflex so food is not pushed back out, the ability to move food to the back of the mouth and swallow, and clear interest in food. Most babies reach this combination around 6 months.
