It's usually been getting ds to sleep that's the problem but not so much now. For a week he has been waking between 1-3am for approx 2/3 hours. He used to wake but could shove a dummy in his mouth and off he'd go. Not now. He's wide awake. Why?!?!?! Can't take it any more. Has this happened to anyone else? He's about to turn 1 x
