My DS, almost 10 months used to be a happy chap, and has been a great independent sleeper. Now, he seems so frustrated and angry all the time, if I am not on the floor playing with him, or when eating. And putting him down for his naps or for the night is a nightmare. He stands up and cries bloody murder, for up to an hour... He pulls his ear, scratches his or my face etc. He does calm down for a minute a two when I re-enter the room, but starts again even if I stay by him (I have done some wi/wo kind of thing previously, when he fights sleep, and it has always worked within minutes). I have even put him in my lap to calm him, and re-do the bedtime routine, but nothing helps. He falls asleep by pure exhaustion.
If it is separation anxiety, what do you do? If no, how can I help him to be his former happy self?
