Oh merry! My 3&1/2 year old boys go through stages like that too. Can you explain to them they are not allowed out of there room until 7am? Maybe buy them a kids clock and make it a big deal for them? Explain that if they wake they can read books but have to stay put? Also do you have quiet time during the day? I find an hour or so wind down just after lunch does wonders. I either read some books or put on a DVD for them but nothing too loud or active. I hope you find some answers as I know how tough grumpy kids can be!!
