I give up. He's almost 2 (Jan) FFS. 1/3 time he's awake for 2 hours during the night, 1/3 time he sleeps through but is up at 5 (and now just screams from waking if he wake early) and 1/3 time he sleeps fine till 6ish. He goes to sleep like a dream at nap and bedtime (7.15) but has always been a nightmare in the night/early waker.
Gradual retreat would just have me sitting in his room for the whole 2 hours and feels like a backward step as at the moment I'm not with him when he falls asleep (but maybe it would be a way out of our hole?). CC we have used at least 3 times to get improvements over the years but now he just gets too overworked and going in just makes him worse.
I don't know what to do - just know I'm sick of the whole damn thing.
