My granddaughter is a night owl and usually weekends won't fall asleep until after midnight if then. She's been that way since 2 or 3 years old. Her excuse: I'm not sleepy. At one time I thought it would benefit the kids, maybe not. Long time since I had little ones. Realize times have changed and maybe I'm just going back too far(when I was a kid especially. With new technology and kids multitasking like we do; who wants to nap.
