When we have the time change, I don't try to get my kids acclimated to it. This way at 6:00 AM when I would normally have a little tyke jumping on the bed to wake me up, now they don't come in till 7:00 AM. The longer I can keep them believing that there hasn't been a time change the longer I can capitalize on the time change.
In contrast, in the Fall when everyone else gains an hour, I work like a madman to get the kids on that schedule, otherwise I'll be woken up at 5:00 AM everyday.
