DS2 has just turned 7 months. About 2 weeks ago he started rolling back to front, and sleeps on his tummy now. Every morning (and I mean every single morning without fail) he wakes up some time between 4 and 5. He's still tired but he will not go back to sleep - he shifts around the cot on his tummy and grunts and whinges (he doesn't roll from front to back, although he used to before he could do back to front). I've tried feeding him and then putting him back, I've tried not feeding him and just putting his dummy back but nothing works. So by the time it's actually morning and DS1 is up, I've been in and out of his room maybe 20 times trying to settle him but it doesn't work. He's then exhausted and his whole routine is out of the window, I'm back at work full time and have to get 2 kids ready and out of the house by 8 so I can commute to London and I'm just completely shattered.
I just don't know what to do, why he's doing this and if there is anything I can try to make him stay in bed longer. I can't go on starting my day at 4.30 every single day. HELP!
