Reflux in newborn babies is very common – after you feed them, it’s not unusual for a bit of milk to come back up (it’s also called spit up or ‘possetting’), and it’s a totally normal process where your baby just brings up a little bit of what they swallowed down their food pipe (oesophagus). Acid reflux is a more uncomfortable and more serious form of this, which can lead to vomiting and weight loss.
