What to do if your baby has reflux

What is reflux?

Baby reflux is very common, and almost all babies will demonstrate some signs of reflux. This can include bringing up small amounts of milk or vomiting, during or soon after a feed. Reflux occurs because the opening between a baby’s stomach and oesophagus (the lower oesophageal sphincter) is weak. This allows the contents of the stomach to freely flow back into the oesophagus. It usually gets better over time, as the sphincter becomes stronger.

How do I know if my baby has reflux?

Babies usually experience reflux before 8 weeks of age, and most reflux improves by 12 months.

Symptoms of reflux in babies include:

  • bringing up milk or being sick during or shortly after feeding
  • coughing or hiccupping when feeding
  • being unsettled during feeding
  • swallowing or gulping after burping or feeding
  • crying and not settling
  • not gaining weight as they’re not keeping enough milk down

Sometimes babies may have signs of reflux, but will not bring up milk or be sick. This is known as silent reflux.

How do I manage my baby’s reflux?

As long as your baby is happy, healthy and growing well, you don’t need to seek medical support for reflux, however there are some things you can do to help manage it.

  • When you feed your baby think about your baby’s positioning, making sure their head is above their tummy.
  • Keep your baby upright for at least 20 minutes after a feed, and let gravity do its job. This is the time to steal those cuddles! If you do need to put your baby down, try to avoid laying them down on their back, as this is when the milk can freely move through a weak sphincter.
  • Don’t over feed your baby. If you are breastfeeding it is difficult to tell how much your baby is getting, and you should feed until baby wants to stop. When bottle feeding however, babies can drink the milk more easily and so may take larger volumes of milk, which then results in vomiting. It is important to give your baby the right amount of milk for their weight, rather than what it says on a formula label. Giving smaller and more frequent feeds can help the milk to stay down better.
  • If formula feeding, think about how you make up a bottle of formula. Ensure you measure the milk powder accurately and follow the instructions on the packet. It is also important to avoid introducing lots of air into the milk, so avoid shaking a bottle to mix it, and try stirring the milk in with a spoon instead. Some bottle teats can let more air in than others so it may be helpful to try anti colic teats.
  • Sometimes reflux can be a sign of cow’s milk protein allergy which would require a discussion with a GP or paediatric dietitian.
