Weaning – starting your baby on solid foods

Introducing your baby to solid foods is often called weaning. This should start when your baby is around 6 months old.


If you are¬†breastfeeding, you don’t need to move to formula milk when introducing solid foods.

We recommend you breastfeed exclusively for 6 months. Continue to breastfeed after solid foods are introduced, up to 2 years or beyond.

When to begin weaning

Babies develop at different stages. Begin introducing solids when your baby is ready. This should be around 6 months. Don’t wean before 17 weeks (4 months).

Why wean between 17 to 26 weeks

You should not give your baby solid foods before 17 weeks because:

  • their kidneys are not mature enough to handle food and drinks other than milk
  • their digestive systems are not yet developed enough to cope with solid foods
  • breast milk or formula milk is all your baby needs until they are 6 months old
  • introducing other foods or fluids can displace the essential nutrients supplied by breast or formula milk
  • introducing solids too early can increase the risk of obesity in later life
  • it can increase their risk of allergy

You should not wait later than 26 weeks (6 months) because:

  • your baby’s energy needs can no longer be met by either breast milk or formula milk alone
  • iron stores from birth are used up by 6 months and their iron needs can no longer be met by milk alone
  • it delays their opportunity to learn important skills, including self-feeding
  • introducing different textures stimulates the development of muscles involved in speech

Signs your baby is ready for solid foods

Between 17 and 26 weeks (4 to 6 months), your baby may begin to show some signs they are ready for weaning. Your baby should show more than 1 of these signs before you think about introducing solid foods, especially if they are 17 weeks.

Signs your baby is ready for solid food:

  • Able to sit up with support and can control their head movements.
  • Not fully satisfied after a milk feed.
  • Demands feeds more frequently for over a week.
  • Shows an interest in food, reaches out for food.
  • Watches others with interest when they are eating.
  • Chews and dribbles more frequently.

These signs show that your baby is ready for you to begin introducing foods other than milk.

Some signs mistaken for a baby being ready for solid foods:

  • Chewing fists.
  • Waking in the night when they have previously slept through.
  • Wanting extra milk feeds now and then.

These are normal baby behaviours and not necessarily a sign of hunger or an interest in solid food.

Starting solid foods will not make your baby any more likely to sleep through the night. Sometimes a little extra milk will help until they are ready for solid food.

Weaning a premature baby

If your baby was born early (before 37 weeks) you should begin introducing foods other than milk sometime between ‘corrected age’ 4 and 6 months. Corrected age, or adjusted age, is your baby’s age minus the number of weeks or months they were born early.

It is important to look for the signs listed above that your baby may be ready for solids.
