Reflux
Many babies bring milk back up through their food pipe at different times of the day or night. This is called reflux (short for Gastro-Oesophageal Reflux, or GOR). Simply put, the valve between the stomach and the food pipe (oesophagus) is not keeping the baby’s milk down and it comes back up the pipe the wrong way. Silent reflux is where milk comes back up from the stomach, but is not vomited out, and is swallowed instead.
