my daughter 5 year old she 2 to 3 days once vomiting empty stomach 4 to 5 times early morning.... ultra sound scan is normal abdomen and pelvis..what reason pls tell me doctor

A. Sometimes it can be associated with acidity also so you can just give some chilled milk like one or two sip in the night before your child goes to sleep this will help and still if the problem is persisting in the morning then you should check with your doctor they will advise you accordingly but I would also suggest you to start the day with a glass of warm water that will also help
