Reflux in babies

Babies often bring up milk during or shortly after feeding and this is known as ‘possetting’ or ‘reflux’. Reflux is just your baby passively ‘spitting up’ whatever they have just swallowed. This is different to vomiting, where the baby's muscles forcefully contract.

Reflux is normal in babies and is usually the result of your baby’s oesophagus, or food canal, not being fully developed. It can be upsetting to parents and it is natural to be worried that something is wrong.

‘A first time mum came to speak to me about her four month old baby. Often after feeding, her baby would bring up a tiny bit of milk and she wanted to know if this was something she should be concerned about.’

Reflux usually stops by the time your baby is 12 to 14 months of age. By this age, the ring of muscle at the bottom of their oesophagus has fully developed and closed off, preventing the stomach contents from leaking out.

Reflux can make your baby upset and irritable, however your baby may be crying for another reason such as hunger, wind, being too hot or too cold, a dirty or wet nappy, tiredness, boredom or simply wanting a cuddle.

‘She asked me if there was anything she could do to prevent her baby from bringing up milk.’

How to Minimise Acid Reflux?

There are some tips to follow to help minimise or prevent reflux, including:

  • Burping your baby regularly during feeding
  • If you are bottle feeding, checking that the hole in the teat isn’t too big as drinking milk too quickly can cause regurgitation
  • Avoiding overfeeding your baby and not forcing them to drink milk that they don’t want – some babies prefer to feed little and often
  • After feeding, hold your baby upright for a period of time

In a small number of cases, reflux may be a sign of a more serious condition such as a milk allergy, gastro-oesophageal reflux disease or a blockage.
