Key takeaways: The AAP, WHO, and Dietary Guidelines recommend starting solids around 6 months, not before 4 months. Look for readiness signs: sitting with little support, good head control, interest in food, and the ability to swallow rather than push food out.
Starting solids is an exciting milestone. Timing matters, and it’s based on your baby’s development, not just age or size.
Why Around 6 Months?
Breast milk or formula provides nearly all of a baby’s nutrition for about the first 6 months (except vitamin D, and possibly iron for breastfed babies). Around 6 months, babies need more iron and zinc than milk alone provides, and their bodies are ready for new textures.
The AAP, the World Health Organization, and the Dietary Guidelines for Americans recommend introducing complementary foods at about 6 months. Starting before 4 months isn’t recommended.
Signs of Readiness
Your baby is likely ready when they:
- Sit up with little or no support.
- Have good head and neck control.
- Open their mouth when food comes toward them.
- Can move food to the back of the mouth and swallow, rather than pushing it out with the tongue (the tongue-thrust reflex fades around 4 to 6 months).
- Show interest in food: watching you eat, reaching for food.
- Can bring objects to their mouth.
Not Signs of Readiness
- Being big for their age.
- Waking more at night.
- Seeming hungrier for a few days (often a growth spurt).
- Reaching age 4 months alone.
What About Cereal in a Bottle?
Don’t add cereal to a bottle unless your doctor recommends it for a specific medical reason. It doesn’t help babies sleep longer and can cause choking and overfeeding.
Getting Ready
- High chair with a five-point harness and a footrest.
- Soft-tipped spoons and small bowls.
- Bibs and a splat mat.
- An open cup or straw cup for small sips of water.
- Infant CPR and choking class.
Allergen Planning
Common allergens like peanut and egg should be introduced early, once your baby is eating some solids. If your baby has severe eczema or a known food allergy, talk to your doctor before starting.
Premature Babies
Premature babies may need to start based on adjusted age and developmental readiness. Follow your pediatrician’s guidance.
Talk to your baby’s doctor if: your baby is 7 to 8 months and shows no interest in food, consistently gags or vomits with solids, has trouble swallowing, or has severe eczema or a family history of food allergy.
The Bottom Line
Most babies are ready for solids around 6 months. Look for developmental signs: sitting, head control, interest, and swallowing.
