Hello, my baby is 10 months old and he fell on backside of his head yesterday, after that he had vomiting within 5 mins. There is no sign of any head injury and he is playing good. Today he had vomiting again after he had his food within half hr, also now he is playing well. Is there any chance to worry about, since he had vomiting twice within 24 hrs? Do I need to consult pediatric? please help
