If they baptized him properly, he is a saint in Heaven.
Baby baptism does nothing. Children have a grace period.
Oh please use your Holy Spirit led common sense, not stick in the mud, dead church traditions of men! So what if the baby might not have gotten baptized(story doesn’t say)...his body and blood were “given up” to help other lives by his Godly parents in which the mother carried the birth thru full term.. That is Christ in action and thus “baptism” enough! I believe God will resurrect him with a wonderful brain added!
