if he roll from side to belly and can lift his head enough to reposition it then he is fine...
as for the spitting up when he is on his back.... as long as his gag reflex is not impaired he will be fine...... some peds recommend that you elevate the head of the crib by putting 1" - 2" blocks under the legs at the head so that babe is sleeping on a little bit of an angle and this will drastically reduce the vomit when he is on his back and then gravity will assist it leaving the mouth area.
I work with a few babies with birth defects where the gag reflex is impaired or non existent and the heads of the beds are raised... always always talk to the doc before making any change
there is also a foam wedge that will go under the mattress to create the same affect
