Tale of a Confused Mom

My children have an alarm that is set for 6:35 Monday through Friday. On Saturday we have a standing 8:30 breakfast date but I let them sleep until the last possible moment. Strangely the past few days they have started getting up before my alarm, not their alarm, but almost an hour earlier than that. What is going on?!?!?! I need that time to do stuff, like shower. This has got to stop.
