My very healthy 7 month old baby throws up forcefully 2 1/2 hours after eating cereal. what is happening?

he probably has Reflux, you need to bring him to his pediatrician and tell him what is going on....its good that you are feeding because formula makes it worse,,,but you dont want him vomiting like this every time he eats....make an appt. with his doctor and he will probably give him some medicine for the reflux....good luck
