Hi Thank you for your query It appears that your daughter has a mild case of gastritis or gastroenteritis. She is bloating up after meals, has retching (hiccups) and then vomits. She also may have a mild degree of gastro-esophageal reflux (food in stomach going back to food pipe i.e esophagus). For the moment she will do well with a few days of anatcids and antiemetics like domperidone. Consult a pediatrician or pediatric surgeon for the appropriate prescription. Avoid large volume meals and try to feed her small frequent meals. Try to keep her upright as much as possible. Make her sleep with a pillow. Avoid spicy and junk food. Prefer simple home made foods. Some cooled milk will help. Hope this helps God bless you
