Vomiting in toddlers: What's normal and What's not? Anything from car sickness to indigestion can cause your child to be sick. Even a prolonged bout of crying or coughing can trigger this reflex. So you may see quite a bit of vomiting in your child’s first few years. In toddlers, a sudden bout of vomiting is most commonly caused by a tummy infection, such as gastroenteritis. This is usually brought on by a virus, which may also give your child diarrhoea. Other reasons for your child vomiting may be: a cold a urinary tract infection (UTI) an ear infection a food allergy Don't have to worry too much but do make sure that he/she drinks lots of water but in small quantity say 2 teaspoon each time.
