Rash baby might have a rash somewhere on his or her body I just figured this out for myself my son was crying terribly so I inspected his hiney and I seen nothing at all until looked a little deeper and it was not a full grown rash but it was growing in and it was just red below his testicles really small and I put some a and d ointment in closed the diaper and he's good as new sometimes rashes can't be seen its just a red area so if u experience a crying baby a diaper change just put dome ointment down there everywhere just to be safecause it's very painful for baby's and they can not talk to tell us what's wrong
