My LO struggle to drink formula when she is awake. She will only drink when she sleeps. Any advice to change her drinking pattern?

I read that when baby needs to be asleep during his or her feed, it could be because eating is painful. Eating while sleeping is not dangerous but it could suggest that baby has Gastroesophageal Reflux Disease (GERD) which requires treatment and this condition needs to be reviewed with the doctor.
