<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 5 month old daughter only eats about 20 oz a day, last time she weighed 2weeks ago 14.7 lbs, she has been diagnosed with acid reflux and is currently taking prevacid twice a day 15 mlg. Is only eating 20 oz OK or should I be concerned? Also, she tilts her head down consistently, she is able to hold it up but primarily holds it down and to the side, this is concerning to me.  <response>: Hi...by what you quote I feel that the kid is having severe form of GER gastroesophageal reflux. The stiffening is called Sanders syn Chat Doctor. Your kid will need -1. Antireflux therapy - Proton pump inhibitors antiemetics2. Always make the kid lie down in a propped up position - as in the care seat. The kid should not be sleeping completely flatly.3. Avoid heavy feeding and feeding more times and in small liquors. Your kid needs expert gastroenterology consultation. Regards -
