5 month old throwing up

my poor baby is throwing everything up. hes not running a temp or anything and he keeps wanting a bottle but right after he drinks one he throws it all up. i dont know whats wrong and i feel so bad any help would be nice

my baby got the stomach flu when he was young like that and so i took him to the hospital because he threw up like 13 times ( i counted b/c im weird like that) and they basicly told me there was nothing they could do because he didnt seem to be dehydrated, i would make an appt with his ped if it continues or at least go to the walk in clinic if you can to make sure he isnt dehydrated and possibly need iv fluids...i hope he gets better soon mama
