When Can Babies Start Eating Solid Food?

The Short Answer

Babies are ready to start solid foods at around 6 months of age — not before 4 months, and ideally not after 7 months. This recommendation is supported by the WHO, AAP, and NHS.

Key Takeaways

• The WHO, AAP, and NHS all recommend starting solid foods at around 6 months — not before 4 months under any circumstances
• Starting too late (after 7–8 months) is associated with iron deficiency, texture aversion, and a narrower flavour window
• All three readiness signs must be present before starting: sits with support, lost tongue-thrust reflex, shows interest in food
• Iron-rich foods are the top priority for first foods — breast milk iron is insufficient after 6 months
• Common allergens (peanut, egg, fish) should be introduced early from 6 months per AAP guidelines to reduce allergy risk

Why 6 Months?

Starting solids too early or too late carries risks:

Too early (before 4 months):

• The digestive system is not mature enough to process solid food
• Increased risk of choking — the tongue-thrust reflex that pushes food out is still dominant
• Associated with higher risk of obesity, food allergy, and digestive upset

Too late (after 7–8 months):

• Increased risk of iron deficiency (breast milk alone no longer meets iron needs after 6 months)
• Harder to accept new textures and flavours, a natural "flavour window" may close
• WHO and AAP both identify 6 months as the ideal introduction point

Signs of Readiness. All Three Must Be Present

Do not start solids based on age alone. Look for all three signs:

1. Can sit up with minimal support and hold their head steady
2. Has lost the tongue-thrust reflex, does not automatically push food out with their tongue
3. Shows interest in food, reaches for food, watches others eat, opens mouth when food approaches

Note: Chewing fists, waking at night, or wanting more milk are NOT reliable signs of solid food readiness.

What Foods to Start With

The best first foods are:

• Iron-rich foods: Pureed meat, chicken, or fish; iron-fortified baby cereal; mashed legumes (lentils, chickpeas)
• Vegetables: Sweet potato, butternut squash, pea puree, broccoli
• Fruits: Pureed or mashed banana, mango, pear, apple
• Healthy fats: Avocado, full-fat yoghurt (plain, from 6 months)

AAP and NHS both recommend introducing allergenic foods (peanut, egg, fish) early (from 6 months) rather than avoiding them, as early introduction reduces allergy risk.

How to Start

• Offer 1–2 teaspoons once daily to start, gradually increasing
• Introduce one new food every 3–5 days to identify any allergic reactions
• Milk (breast or formula) remains the primary nutrition source until 12 months
• Never add salt, sugar, or honey to baby's food
• Expect mess and refusal, it takes 10–15 exposures for some babies to accept a new food

What to Avoid Under 12 Months

• Honey (risk of infant botulism)
• Cow's milk as a main drink (formula or breast milk only)
• Whole nuts (choking hazard)
• Added salt and sugar
• Certain fish high in mercury (shark, swordfish, tilefish)

Frequently Asked Questions

When can babies start eating solid foods?

Babies are ready for solid foods at around 6 months — not before 4 months. The WHO, AAP, and NHS all recommend around 6 months as the ideal starting point. Starting before 4 months is unsafe regardless of readiness signs.

What are the signs that my baby is ready for solids?

All three signs must be present: baby can sit up with minimal support and hold their head steady; has lost the tongue-thrust reflex (no longer automatically pushes food out with their tongue); and shows clear interest in food by reaching, watching others eat, and opening their mouth. Chewing fists, waking at night, and wanting more milk are not reliable indicators.

What are the best first foods for babies?

Iron-rich first foods are a priority — pureed meat, chicken, iron-fortified baby cereal, and mashed lentils. Good vegetable options include sweet potato, butternut squash, and broccoli. Fruits such as banana, mango, and pear work well pureed or mashed. The AAP and NHS recommend introducing allergens (peanut, egg, fish) early from 6 months to reduce allergy risk.

How much food should I give a baby starting solids?

Start with 1–2 teaspoons once daily and increase gradually over several weeks. At 6–7 months, most babies eat a few tablespoons at one meal per day. By 9–12 months, the goal is 3 meals per day of varied foods. Breast milk or formula remains the primary nutrition source until 12 months.

How do I know if my baby is allergic to a new food?

Introduce one new food every 3–5 days and watch for allergic reactions: hives, rash around the mouth, swelling, vomiting, or difficulty breathing. If a mild reaction occurs, stop that food and consult your doctor before reintroducing it. A severe allergic reaction (anaphylaxis) is a medical emergency — call emergency services immediately.

Is it safe to start solids at 4 months?

No — starting before 4 months is associated with increased risk of choking (the tongue-thrust reflex is dominant), digestive problems, food allergy, and obesity. The digestive system is not mature enough to handle solid foods before this age. The AAP advises waiting until around 6 months when all readiness signs are present.

Can I start with purees or should I go straight to finger foods?

Both approaches are supported by the AAP and NHS. Traditional weaning starts with smooth purees and gradually progresses to lumpier textures and finger foods. Baby-led weaning skips purees and starts with soft finger foods from the beginning. A combination approach — some purees and some finger foods — also works well for many families.
