The transition to solid foods is one of the most anticipated milestones of the first year — and one of the most confused. Parents receive conflicting advice about when to start, what to offer first, whether to use purees or finger foods, and how much baby should actually eat. Here's the clear, evidence-based guide to starting solids: the right timing, the signs of readiness, what to offer, and how the first weeks actually look.
When Do Babies Start Eating Baby Food?
Current guidance from the American Academy of Pediatrics (AAP), the World Health Organization (WHO), and most major pediatric bodies aligns on around 6 months as the appropriate time to introduce solid foods, with a window of 4–6 months for babies showing clear readiness signs.
The key word is "around" — the calendar date matters less than the readiness signs. A baby who shows all readiness signs at 5.5 months is ready; a baby who hasn't developed them at exactly 6 months is not.
Signs of Readiness for Solid Foods
All of the following should be present before starting solids. These are developmental readiness indicators, not suggestions:
- Sitting with minimal support: Baby can sit upright with limited help and hold that position. This is essential for safe swallowing.
- Good head and neck control: Head is steady without support. An unsteady head during feeding is a choking risk.
- Loss of the tongue-thrust reflex: Newborns reflexively push objects out of their mouths with their tongue. This reflex must have faded for solids to work — if you put a spoon in and the food comes straight back out, the reflex is still active.
- Interest in food: Watches food intently, reaches toward it, opens mouth when food approaches. This is a behavioral readiness sign.
- Doubling of birth weight: A rough but useful marker of physical maturity. Most babies hit this around 4–5 months.
Starting before 4 months is not recommended regardless of readiness signs — the gut and immune system aren't mature enough. Starting after 7 months without a medical reason may make acceptance of new textures and flavors harder.
First Foods: What to Offer
The evidence no longer supports the traditional "rice cereal first, then yellow vegetables, then orange, then meat" approach. Current guidance is more flexible:
- Any single-ingredient food is an appropriate first food — there's no required order
- Iron-rich foods should be prioritized early: Iron stores from birth begin depleting around 6 months. Iron-fortified cereals, pureed meat, and legumes address this directly
- Allergen introduction should happen early: The LEAP study and subsequent research demonstrated that early introduction of the top allergens (peanut, egg, tree nuts, fish, wheat, milk) reduces allergy risk rather than increasing it. Current AAP guidance recommends introducing allergens early and regularly
- Variety is beneficial from the start: Exposure to a wide range of flavors and textures in the first months of solids increases acceptance later
A Simple First Month of Solids Schedule
| Week | Frequency | Amount | What to Offer |
|---|---|---|---|
| Week 1–2 | Once daily | 1–2 teaspoons | Single-ingredient purees: sweet potato, pea, banana, avocado |
| Week 3–4 | Once or twice daily | 2–4 teaspoons | More variety; introduce iron-rich foods; begin allergen introduction |
| Month 2 | 2–3 times daily | 2–4 tablespoons | Multi-ingredient purees; more textures; established allergen foods |
| 7–9 months | 3 times daily | 4–6 tablespoons per meal | Mashed and lumpy textures; soft finger foods emerging |
Purees vs. Baby Led Weaning
Both approaches work. The evidence doesn't clearly favor one over the other for nutritional outcomes, and many families combine both ("baby-led weaning with purees," sometimes called "combination feeding").
Traditional purees: Smooth textures that are easiest to manage initially; more control over exact foods and quantities; useful for allergen introduction where precise amounts matter.
Baby led weaning (BLW): Soft, age-appropriate finger foods offered from the start, allowing baby to self-feed. Builds independence and texture tolerance; requires appropriate food preparation (soft enough to mash between two fingers, never round hard chunks).

What Not to Offer Before 12 Months
- Honey: Risk of infant botulism. Absolute contraindication under 12 months.
- Cow's milk as a main drink: Fine in foods and cooking; not as a replacement for breast milk or formula before 12 months.
- Added salt: Baby kidneys can't process it. No salt in any form in foods prepared for babies under 12 months.
- Added sugar: No benefit and trains preference for sweetness. Avoid.
- High-mercury fish: Swordfish, shark, tilefish, king mackerel. Low-mercury fish (salmon, cod, tilapia) is excellent and recommended.
- Choking hazards: Whole grapes, whole cherry tomatoes, raw carrot coins, whole nuts, large chunks of any firm food.
How Much Should a Baby Eat at First?
Very little — and that's completely normal. In the first weeks of solids, the purpose is exploration, not nutrition. Breast milk or formula remains the primary nutrition source until around 8–9 months, when solid food intake gradually becomes more substantial. A baby who eats 2 teaspoons of sweet potato and then pushes the bowl away is not failing at solids — they're doing exactly what they should be doing.
