Starting Solids at 6 Months: Readiness Signs, First Foods, What to Avoid, and Choking vs Gagging

Start solids around 6 months when your baby can sit with head control and shows interest in food — vegetables, soft fruits, meat, eggs, one new food every 3–5 days. Breast milk or formula stays the main source of nutrition. Hard rules: no honey (under 1 year — botulism risk), no juice, no salt or sugar, and no choking-hazard foods.

Your baby just turned 6 months. What can they eat, how much, and what's off-limits? It's the most-asked question of the 5–7-month parent group — and the answers from grandparents, doctors, and the internet don't agree.

This article distils what WHO [1], AAP [2], NHS [3], and Samitivej Hospital [4] recommend — including the now-settled science on introducing allergens at 6 months instead of waiting, which still surprises many families.

When to Start — 6 Months Is the Standard

WHO [1] recommends exclusive breastfeeding for the first 6 months, then introducing complementary foods alongside continued breastfeeding through age 2 or beyond:

"an infant's need for energy and nutrients starts to exceed what is provided by breast milk"

By around 6 months, breast milk alone can no longer cover the energy, iron, and zinc your baby needs.

AAP [2] agrees: start around 6 months (generally not before 4 months, and not much later than 6).

Real Signs of Readiness

Age alone isn't enough — your baby also needs physical readiness. AAP [2] lists 4 signs:

1. Head control — "Can they hold their head up?" Sitting upright in a feeding chair.
2. Interest in food — "Do they open their mouth when food comes their way?" Watching you eat, opening their mouth on cue, reaching for your plate.
3. Swallowing reflex — "Can they move food from a spoon into their throat?" No longer pushing food out with the tongue (the extrusion reflex has faded).
4. Big enough — "double their birth weight (typically at about 4 months of age) and weigh about 13 pounds or more" (~5.9 kg).

If all four aren't there, wait. Don't rush.

What "Complementary Food" Means

The term complementary food (or "starting solids") is what babies start eating around 6 months alongside continued breast milk or formula — not instead of it. Solids start small and gradually become a larger share of nutrition through year one.

First Foods — Where to Start

Principle: One at a Time, Wait 3–5 Days

AAP [2]:

"Introduce one 'single-ingredient' new food from any food group every 3 to 5 days. Look out for any reactions."

Try one new food at a time, wait 3–5 days for allergic reactions (rash, hives, diarrhoea, vomiting, breathing difficulty), then try the next.

Lead with Vegetables and Iron-Rich Foods

NHS [3] recommends non-sweet vegetables before fruit:

"Start weaning with vegetables that aren't so sweet, such as broccoli, cauliflower and spinach."

Why: babies who get sweet foods first sometimes refuse vegetables later.

AAP [2] is emphatic about iron and zinc:

"foods that provide iron and zinc, such as baby food made with meat or iron-fortified cereals."

The iron stores your baby was born with start running out at 6 months. Breast milk alone won't refill them — iron-rich foods are non-negotiable to prevent infant anaemia.

Good First-Food Options

• Vegetables (steamed, mashed) — broccoli, cauliflower, spinach, pumpkin, carrot, sweet potato
• Soft fruits (mashed) — banana, avocado, steamed apple, pear
• Meat (mashed) — chicken, pork, beef, liver (highest in iron)
• Egg yolk or whole egg — fine from 6 months (see § Allergens below)
• Iron-fortified infant cereal — mixed with breast milk or formula to a thin consistency
• Pulses (mashed) — peas, mung beans — protein and iron

Frequency and Amount — Small, Then Build

NHS [3]:

"To start with, your baby only needs a small amount of solid food, once a day."

Start with 1 meal/day, just 1–2 teaspoons. Their main calories still come from breast milk or formula.

WHO [1] frequency guide:

NHS [3] is clear that solids do not replace milk:

"Your baby's main source of nutrition is still breast milk or first infant formula, so keep offering it to your baby on demand."

Allergens — Introduce at 6 Months, Don't Wait

This is what's changed from older advice. AAP [2] is unambiguous:

"There is no evidence that waiting to introduce baby-safe (soft) foods, such as eggs, dairy, soy, peanut products or fish, beyond 4 to 6 months of age prevents food allergy."

Waiting to introduce eggs, peanut, cow's milk, or fish does not reduce allergy risk — and recent research suggests early introduction may actually lower the risk for some children, especially peanut allergy in high-risk infants.

Common Allergens (Try One at a Time, Watch for Reaction)

• Eggs (well-cooked whole egg)
• Cow's milk and dairy (yoghurt, cheese — but not cow's milk as a drink replacing breast milk or formula until age 1)
• Peanut (smooth peanut butter thinned into purée — never whole peanuts or chunks — choking hazard)
• Other tree nuts (almond, cashew — finely ground only)
• Fish and shellfish (salmon, tilapia, mashed shrimp)
• Soy (tofu)
• Wheat / gluten
• Sesame

NHS [3]: once introduced and tolerated, keep offering regularly — "Once introduced and if tolerated, keep offering those foods as part of your baby's usual diet (to minimise the risk of allergy)." Stopping and restarting can re-trigger allergy.

Signs of an Allergic Reaction

• Red rash around mouth, cheeks, or body within minutes to 2 hours
• Vomiting, diarrhoea after eating
• Swelling of face, lips, or tongue
• Wheeze, cough, difficulty breathing — call 1669 immediately (possible anaphylaxis)

If your family has a history of severe allergy, or your baby has significant eczema, talk to a paediatrician before introducing peanut.

Hard "Do Not Feed" List

❌ Honey — under 1 year

AAP [2] lists honey as off-limits under 1 year because of infant botulism — Clostridium botulinum spores in honey can cause life-threatening paralysis in infant guts.

Banned in any form:

• Plain honey
• Foods containing honey (including breads with honey)
• Honey-lemon tea — even a single sip

❌ Juice — under 12 months

AAP [2]:

"Babies do not need juice. Babies younger than 12 months should not be given juice."

Babies who fill up on juice miss nutrients and risk early tooth decay before all teeth have erupted.

❌ Salt and Sugar

NHS [3]: no added salt or sugar in baby food. Infant kidneys can't handle sodium loads, and added sugar promotes sweet preference and decay.

❌ Cow's Milk as a Drink (until age 1)

Cow's milk is fine as an ingredient (yoghurt, cheese in food). It is not a drink replacement for breast milk or formula in the first year — the protein and mineral load strains the kidneys, and the iron content is too low.

❌ Choking Hazards (under 4 years)

AAP [2] lists, for under-1s, foods to avoid:

"hot dogs, nuts and seeds, chunks of meat or cheese, whole grapes, popcorn, chunks of peanut butter, raw vegetables, and fruit chunks."

In practice:

• ❌ Hot dogs, sausages, whole meatballs
• ❌ Whole nuts, whole peanuts
• ❌ Whole grapes, whole cherries (quartered is OK)
• ❌ Popcorn
• ❌ Chunks of meat or cheese
• ❌ Globs of peanut butter (thin into purée — fine)
• ❌ Hard raw vegetables (raw carrot sticks, celery)
• ❌ Large fruit chunks

Choking vs Gagging — Know the Difference

This is what scares parents most when starting solids — but most of what you'll see is gagging (a protective reflex), not choking.

Gagging is a protective mechanism that pushes oversized food forward — totally normal, don't suppress. Choking is food blocking the airway — emergency.

Every household with a young child should know back blows + chest thrusts for infants. Take an infant CPR course or watch the Red Cross / AAP video at least once.

How to Feed — Spoon or Baby-Led Weaning

There are two common approaches — both are fine:

1. Spoon-Feeding (Purées)

Traditional. Mash food smooth, use a soft silicone spoon, gradually introduce thicker textures.

2. Baby-Led Weaning (BLW)

Baby self-feeds with hands from the start. Foods must be finger-food shaped (steamed vegetable batons, soft fruit pieces sized for a baby's grip) — no purées.

Both approaches deliver the same nutrition. Pick what suits your family — or mix both.

WHO [1] cares less about method than about responsive feeding:

"feed slowly and patiently, encourage them to eat but do not force them, talk to the child and maintain eye contact."

Watch your baby's face. Mouth open = next bite. Head turned away = stop. Don't force-feed because they didn't finish the bowl.

When to Talk to a Doctor

• Your baby is 7+ months and still completely refusing solids — pushing everything out, mouth clamped shut
• No weight gain or weight loss after starting solids
• Repeated vomiting after specific foods
• Significant eczema before starting solids — discuss peanut and egg approach first
• Your baby was born preterm — use corrected age, not chronological age

Summary

1. Start around 6 months when head control, interest in food, swallowing, and weight are all there — not before 4 months, not much later than 6
2. First foods = non-sweet vegetables + iron-rich foods (mashed meat, liver, fortified cereal). One new food at a time, 3–5 days between
3. Amount starts at 1–2 teaspoons/day, builds to 2–3 meals by 8 months — breast milk / formula stays primary
4. Allergens (egg, peanut, cow's milk, fish) — introduce at 6 months, don't wait. Waiting doesn't reduce allergy risk
5. Banned: honey (under 1 — botulism), juice (under 1), salt and sugar, cow's milk as a drink (under 1), all choking-hazard foods
6. Choking ≠ gagging — gagging is normal, watch and wait. Choking is silent, blue, immediate first aid + 1669
7. Spoon-feed or BLW — either works. Follow the baby's lead. Don't force
