Solids – when do we start?

Starting solids is a big step for you and your baby. There’s a lot of advice out there, so it can be hard to know what’s right. The good news is, health experts have clear, evidence-based recommendations to help you.

Here’s what the major health authorities say about when to introduce solids.

Australia’s National Health and Medical Research Council (NHMRC):¹

• Advises exclusive breastfeeding for around the first 6 months.
• After 6 months, continue breastfeeding alongside complementary foods for at least 1 year, or as long as mother and child desire.

World Health Organization (WHO):²

• Recommends exclusive breastfeeding for the first 6 months.
• After 6 months, continue breastfeeding alongside complementary (family) foods for 2 years or beyond.

These recommendations are based on research into what babies need to grow and stay healthy. It’s important to wait until your baby shows signs that they’re ready, because starting solids too early can cause problems. Watching for these signs and following the guidelines helps give your baby the best start.

Every baby develops at their own pace but most will show these signs at around 6 months:

• Sitting upright with little support.
• Good head and neck control.
• Showing interest in your food (reaching for it, watching you eat).
• Losing the tongue-thrust reflex (not pushing food out with their tongue).

If your baby isn’t showing all these signs yet, that’s okay. Some babies are ready a little earlier and some a little later.

You might hear advice to start solids before 6 months but there are good reasons to wait until your baby is ready. Here’s why:

• Your baby’s tummy isn’t ready: Young babies’ digestive systems can’t cope well with the fats and proteins found in other milks, eggs, meat, fruit, vegetables and cereals.
• Kidneys need time: Babies’ kidneys aren’t able to handle the large amount of salt found in many processed foods.
• No sleep benefit: Starting solids early won’t help your baby sleep through the night. Research shows there’s no difference in night-waking between babies under 6 months who have solids and those who have only breastmilk.³ In fact, some babies sleep worse if solids upset their tummy.
• Allergy risk isn’t reduced: There’s no good evidence that starting solids earlier means less chance of allergies.⁴ The timing of solids is just one factor.  Your baby’s overall development and readiness matter too.
• Breastmilk protects against illness: Breastfeeding helps protect babies from illness, even in developed countries like Australia.⁵ Waiting to introduce solids helps keep this protection strong.
• Guidelines consider more than allergies: When experts set guidelines, they look at babies’ nutritional needs, ability to chew and swallow safely, risk of getting too little breastmilk and risk of illness or infection.

In summary: Waiting until around 6 months helps make sure your baby is ready for new foods, keeps breastmilk as their main source of nutrition and supports their health and development.

It’s common to get advice from family and friends to start solids early. They mean well but your baby’s readiness is what matters most. Trust your instincts and the evidence. If you’re ever unsure, a chat with an ABA breastfeeding counsellor or educator can help. 

When your baby is ready, make mealtimes relaxed and enjoyable. Let your baby join family meals, even if they’re not eating much yet. Prepare for mess. Try a bib with a catcher, a mat under the chair, and a relaxed attitude. Respect your baby’s tastes and interest. Some days they’ll eat more, some days less, and that’s perfectly normal.
