I think DS(3) has decided he doesn't need a day nap anymore...
I had to wake him up from his nap last Wednesday and he hasn't had a nap since. The first two days he was fine with having quiet time in his room while his sister napped (yes, that's right, I JUST got them sleeping at the same time). But the last three days he just comes out every 5 mins and when I get grumpy and tell him in no uncertain terms 'don't come out again' he sits there quietly for ages, and then the next thing I know, he has woken his sister (by emptying the toy bucket in her cot).
If I lock his door, he just tells and yells, and that wakes his sister even quicker.
They both were sleeping at least 2hours last week, this week, nothing. She gets about 40mins til he decides she needs to get up too, which makes her a nightmare for the rest of the day, and especially bed time.
*sigh* just when you get comfortable and think things are going your way.
How have your kids 'shown you who is boss'?
