Our oldest (1K) has been wanting to stay up longer with us lately. It's nearing the 10 o'clock hour and he was finding any excuse to stay awake. Finally, I told him that at his age he needs to get a minimum of 10 hours of sleep a day. That means he won't be able to get out of his bed until 8 tomorrow morning. If he wanted to stay up til 11 he can't get out until 9 o'clock in the morning. "Now, do you want to stay up late or go to bed," I asked. "I want to go asleep," he replied. Mission Accomplished.
