Who needs sleep?

Kalianna has decided she's done sleeping. I think it's too boring for her. There are many other things she'd much rather be doing. Twenty months seems early to me to stop napping, especially because there are some days I know she needs it, but she's done. She still has "quiet time" in her room. But she simply sits in bed and talks to herself for a couple hours a day. No sleeping. She has taken one nap in the last two weeks. But now it's also creeping into bedtime. Last night we put her to bed at 9:00, as usual. She didn't fall asleep until after 11:00pm. I'm not sure how she does it! I need sleep! But she seems perfectly happy to go for days with no naps and going to bed super late. Silly girl!
