When and how to start solid foods: a calm guide for new parents

By the MammaFlow team · Updated October 25, 2026 · 8 min read · All guides

Spoons, bibs, mashed things flicked across the kitchen — starting solids is one of the great messes of early parenthood. It's also surprisingly simple once you know the readiness signs and a few first foods that work. Here's the calm version, plus how to keep track of what your baby eats without turning meals into a spreadsheet.

When is baby ready for solids?

Most babies are ready around 6 months — not before 4 months, and the exact timing is individual. Look for a combination of signs:

• Sits with support and holds their head steady
• Leans forward, opens their mouth for food and watches you eat with fascination
• Has lost the tongue-thrust reflex (food doesn't get pushed straight back out)
• Can pick up objects and bring them to their mouth

Milk — breast or formula — remains the main nutrition source through the first year. Solids at the start are practice, not volume.

The best first foods

There's no required order. Soft, iron-rich and simple wins:

• Iron-rich firsts: well-cooked lentil dal, soft shredded meat, iron-fortified cereal, mashed beans.
• Fruits & veg: mashed banana, avocado, sweet potato, carrot purée, steamed apple, pumpkin.
• Finger foods around 6–7 months: soft steamed broccoli florets, ripe banana sticks, well-cooked pasta — baby-led weaning style.

Texture matters more than the specific food: smooth purées first, then thicker and lumpier within weeks. Start with one meal a day (a teaspoon or two) and let appetite lead.

Introducing common allergens

Current guidance is to introduce common allergens early and often, usually from around 6 months, once a few bland foods are tolerated: egg, peanut, wheat, milk products, soy, fish, sesame and tree nuts. The practical version:

1. Introduce one allergen at a time, in the morning, when you can watch for reactions.
2. Start with a small amount, then gradually increase over a few days.
3. Keep it in the diet regularly once tolerated — continued exposure matters.
4. If there's a family history of allergies or baby has eczema, talk to your pediatrician first.

Signs of a reaction: hives, swelling (especially face or lips), vomiting, wheezing or unusual lethargy. Mild localized redness often isn't an allergy — but severe symptoms mean you stop and seek medical help immediately.

Tracking foods, nutrition and reactions (without the spreadsheet)

Two things are genuinely worth logging once solids start:

• What food, when, how much — a food history turns "has she had egg?" from guesswork into a glance.
• Reactions — liked, neutral, disliked or flagged allergy per food builds a record your pediatrician will actually thank you for.

This is exactly why we built the solid food tracker in MammaFlow. Log any food and the AI instantly adds calories, carbohydrates, protein, fat and fiber per 100g, key nutrients, benefits for baby and safety tips — typical serving sizes, choking guidance and allergen flags included. The nutrition card is cached, so every food is looked up once and reused forever. Your food history groups by day, and stats show variety, servings this week and most-loved foods at a glance.

A gentle first-week plan

1. Day 1–2: one soft food at one meal (mashed banana or lentil dal). A teaspoon is a success.
2. Day 3–4: repeat the same food; watch for reactions.
3. Day 5–7: add a second food at the same meal; keep portions tiny.
4. Week 2 onward: add one allergen (e.g. well-cooked egg), move toward two meals a day, thicken textures.
