For the past few nights my son has been falling asleep and waking up shortly after screaming. Well...he doesn't even wake up really, he just starts screaming and crying out of the blue but I can't get him to wake up and I can't calm him down?? I was thinking maybe he's been having night terrors but he's so little? Idk what it is. Has this happened to any other mamas when their babies were still baby babies?
