changing sleeping patterns

I just put my little girl to bed time. She sleeps late these days because she also naps late. Her sleeping patterns are really changing. I am finding it more difficult to put her on her nap in the afternoon. Her nap time is usually at 1:00 PM, but she will just goof in her bedroom. Sometimes, I would think that she is already napping soundly only to realize that she is just playing in her bedroom all along. Geez, baby girl! But she is always good with her nap most of the time and I hope that it will continue to be that way for a longer time. Have a goodnight all, guys!
