Hello, just wondering if anyone has had this. Don't know if it's normal and if we should see a doctor. My son is 4.5 now and he's always had random vomiting. Went to nursery and has just started school. Every couple of months he vomits once , no other symptoms at all and no one else ever gets it. Doesn't seem to be anxious. Doesn't occur after certain foods. Is this a thing with young kids? Thanks in advance.
