Trey has a clock in his room. The rules are: he can come out from afternoon nap when the first number is a 3, and come out in the morning when the first number is a 7. This works about 75% of the time. Last night I was asleep and felt a little body climbing up on the bed. It crawled all the way up to the pillow. Little arms hugged me, and Trey sweetly said "good morning mommy. I love you. the first number is 3!" Sure enough I checked my clock and it was 3:01am.
