Oh yeah, they are fine at quiet time because I do allow them to bring ipods, ds and such for that reason...as long as I don't hear the electronics, then I'm fine with it. I think the problem is that the younger ones are so used to the routine during the day and are really good for "going with the flow". I try to keep them busy with crafts, games and activities, but as someone else said, they get bored very easily.
I think I will just hope that the nice weather comes fast so I can get them outside for longer periods of time to get some of that energy out, lol.
