Will try to keep this brief...
Ds (almost 11 mo) slept through from 5m then had separation anxiety at 9m which buggered everything up. Did gradual retreat sleep training which worked well but we have been left with a wake-up every morn on the dot of 4.30. We tried gradual retreat at this time but didn't really work (30 mins standing there for max 30 mins more sleep) so I gave up and for about 2 months now have brought ds into bed with me. He'll get an extra 1-1.5 hrs that way but it's not restful for him as he's very restless during this time. And I don't get back to sleep on account of the slapping, kicking etc that is my fidgety baby and dh takes all the cover 
I am losing my mind starting my day at 4.30. Ds VERY full on and active during the day so I'm just permanently shattered. And the last few mornings I've been really grumpy with ds because of lack of sleep and slapping etc and I hate being a grump with him!
Any advice on how to stop the habit of this wake-up? When he was sleeping through he would fairly often stir at some point between 4-6 but would either self settle or we would give him a dummy and he would happily go off again for another hour at least. Now the moment he wakes he's standing at the cot and wailing like a banshee. Just don't know how to stop this, and ds def needs more sleep - as do I!
