Introducing solid foods to your baby? Our step-by-step guide covers readiness signs, best first foods, allergen introduction, and sample schedules.

Key Takeaways

Most babies are ready for solids around 6 months
Prioritize iron-rich first foods like meat, lentils, and fortified cereal
Introduce top allergens (peanut, egg, dairy) early to reduce allergy risk
Both purees and baby-led weaning are safe and effective approaches
It may take 10-15 exposures for a baby to accept a new food

Introducing solid foods to your baby is an exciting milestone — and a confusing one. Should you start with rice cereal or avocado? Spoon-feed purees or try baby-led weaning? When is it safe to offer peanut butter? This step-by-step guide walks you through everything you need to know to start solids confidently and safely, based on the latest AAP and WHO recommendations.

Step 1: Know When Your Baby Is Ready

Most babies are ready to start solids around 6 months of age, but readiness depends on development, not just the calendar. Look for these signs:

Sits upright with little to no support
Has good head and neck control
Has lost the tongue-thrust reflex (no longer pushes food out automatically)
Shows interest in your food — reaching, opening mouth, watching you eat
Can move food from a spoon to the back of the mouth and swallow

If your baby is missing one or two of these, wait another week or two. Starting too early (before 4 months) is linked to higher risk of obesity and allergies; waiting too long (past 7 months) can lead to feeding difficulties and iron deficiency.

Step 2: Choose Your Approach

There are two popular methods for introducing solid foods to baby:

Traditional purees: You spoon-feed smooth, single-ingredient purees, gradually adding texture.
Baby-led weaning (BLW): You offer soft, finger-sized pieces of food and let baby self-feed from the start.

Both are safe and supported by research. Many families use a blended approach, offering purees at some meals and finger foods at others. Pick whichever fits your lifestyle and your baby's temperament.

Step 3: Start with Iron-Rich First Foods

Iron stores from pregnancy start running low around 6 months, so prioritize iron-rich foods from day one. Great first foods include:

Pureed or shredded soft-cooked meat (chicken, beef, turkey)
Iron-fortified single-grain infant cereal mixed with breastmilk or formula
Mashed lentils, beans, or tofu
Mashed avocado, banana, sweet potato, or pear
Soft-cooked broccoli florets or carrot strips (for BLW)

Introduce one new food at a time and wait 2-3 days before adding another, so you can spot any reactions.

Step 4: Introduce Common Allergens Early

Current guidelines from the AAP and NIH recommend introducing the top allergens between 4 and 6 months to reduce allergy risk:

Peanut (thin smear of smooth peanut butter or peanut puff)
Egg (well-cooked, mashed)
Dairy (full-fat yogurt — not cow's milk as a drink until 12 months)
Wheat, soy, tree nuts (as butters), fish, and shellfish

Offer each allergen at home, earlier in the day, when you can watch for reactions. If your baby has severe eczema or an existing food allergy, talk to your pediatrician about an allergist-supervised plan.

Step 5: Build Up Frequency and Variety

A reasonable progression looks like this:

6-7 months: 1-2 small meals a day, 1-2 tablespoons each. Milk (breast or formula) is still the main nutrition source.
8-9 months: 3 meals plus a snack, with more texture (mashed, lumpy, soft finger foods).
10-12 months: 3 meals and 1-2 snacks, mostly table foods, family meals.

Always avoid honey (before 12 months), choking hazards (whole grapes, popcorn, nuts, hot dogs), added sugar, and excessive salt.

Step 6: Make Mealtimes Positive

Babies are messy, slow, and unpredictable eaters. Sit them upright in a high chair, eat with them when possible, and let them touch, squish, and explore. If they refuse a food, try again another day — it can take 10-15 exposures before a baby accepts a new flavor.

When to Worry

Call your pediatrician if you see hives, swelling, vomiting, or breathing trouble after a new food. Also reach out if your baby consistently gags severely, refuses all solids past 8 months, or isn't gaining weight. Introducing solid foods is a journey — not a race — and small, steady steps build a confident, adventurous eater.

Frequently Asked Questions

What is the best first food for a baby?

Iron-rich foods like pureed meat, iron-fortified cereal, lentils, or mashed beans are ideal first foods. Mashed avocado, banana, and sweet potato are also excellent gentle options.

At what age should I start introducing solid foods?

The AAP recommends starting around 6 months, when your baby shows signs of readiness like sitting up, head control, and interest in food.

Is baby-led weaning safe?

Yes, when done correctly with appropriately sized, soft foods and a baby who can sit upright independently. Always supervise meals and learn the difference between gagging (normal) and choking.
