Tonight, I went upstairs and noticed Chloe's light on. She, however, was not in her room (my kids had gone to bed about an hour before). I went into Caleb's room, and he and Chloe were playing in his bed (Luke was sleeping). When I asked what she was thinking, she replied,
"Caleb said I could come in."
Oh, ok. Apparently, the four year old is in charge now.
