Interesting... Our Mr 3 often wakes up and plays in the middle of the night, I've always just left him. Bad mummy here clearly! I can't force him to sleep, he doesn't have a day sleep and I can't use the cot threat as we now have DS2 in the cot but also DS1 can climb out of it, soooo, wouldn't work for us

If he needs something he comes down to us but most times I just hear him awake and he's just chatting away... In the morning I can find toys etc in his bed. But he's always happy enough...

I do go get him if he gets out of bed and turns lights on around the house, but mostly he just stays in his room so I just leave him be.

We do have a gro clock, which has stopped the 5am wake ups, but he still parties overnight!
