Total accident, I walked out of the kitchen as DH walked in carrying DS and the door caught him on the side of the head. He cried a little but was fine and although I felt awful I kind of forgot about it. He's not been himself today, sleeping loads during the day, off his food and although he's usually asleep by 10ish he's still awake and screaming. Have I really hurt him? Do I need to take him to hospital? :(
