Your SON will need - 1. Antireflux therapy - Proton pump inhibitors antiemetics2. Always make him lie down in a propped up position - as in the care seat. He should not be sleeping completely flatly.3. Avoid heavy feeding and feeding more times and in small liquors. He needs expert gastroenterology consultation. Regards -
