DS is 21 months old and has always been a reasonable sleeper. He goes to bed around 7/7.30pm and usually falls asleep pretty quickly. For the last month or so he's screamed if we leave the room too fast at llights out, and so I/we have taken to telling him that we'll stay for 5 minutes by the door and then leave. This usually works.
However, for the last few weeks he's started waking early - around 5am and doing the same thing - screaming until one of us goes to his room. We can then usually settle him easily, but if we try to leave he'll scream again. There's nothing wrong with him - he has his dummy, duvet is in place, etc etc. We've taken to one of us dozing in the spare bed in his room once he wakes up like this - just to get some extra rest! He generally doesn't go back to sleep, but will at least doze or lay quietly till around 6.30am when we're happy to get up.
I've really started to have enough of this sleeping thing though. I'm 5 months pregnant with DC2 and working full time, so really want some more sleep. DS is certainly not waking up hungry (doesn't matter if he eats loads of dinner or none - always the same problem), and we've tried putting him to bed later, but still have the same problem. He's in creche full time, so is still having one nap at lunchtime of around 1-2 hours. But even if he doesn't nap at the weekend he'll still do the same thing.
Does anyone have any advice? I'm not sure that sleeping in his room is a good habit to be getting into, but if we leave him to cry he just climbs out of the cot. We're going to take the side down at the weekend and see what happens. But I'm worried that this will make things worse, as he'll be able to come into our room (we live in a flat). I'm really exasperated about the whole thing, so if anyone has any suggestions, I'd be very grateful! I'd just like him to get back to waking around 6.15am like he used to....
