Is it possible for babies as young as 4mths to have nightmares? My partner is prone to them, will wake screaming in the night. Tonite our daughter did the same, woke with a noise of pure terror, and continued screaming until she was fully awake. Gave her a bottle (which she ate all of, which she doesn't do in middle of night anymore) and is now going back to bed. Anyone else experience anything like this? Was this just her waking really angry to feed? Nightmare? Reaction cuz of her 4mth shots?
