You can give him Rantac (150 mg) 1/2 tablet twice a day for 2 -3 days before food. You should give him very soft bland overcooked food for now, something like curd rice (if he tolerates dairy well)/ chicken broth and rice/ egg white and rice. Try to avoid feeding for at least an hour after he vomits, and feed him in parts by dividing your meal into multiple smaller meals. Avoid fruits and vegetables for 2-3 days. Get him examined if the vomiting persists or progresses into gastroenteritis.
