Hi...by what you quote I feel that the infant is having sever form of GER (gastroesophageal reflux). The stiffening is called Sanders syn Chat Doctor.  Your daughter will need - 1. Antireflux therapy - Proton pump inhibitors + antiemetics2. Always make her lie down in a propped up position - as in the care seat. She should not be sleeping completely flatly.3. Avoid heavy feeding and feeding more times and in small liquors.4. This type of GER is the root cause for the constipation she is having. She needs expert gastroenterology consultation. Regards -
