I'm not sure how long this has been going on but has been since before Christmas for sure. DD will go in her bed and just talk and play. For hours!! I've tried putting her down anywhere from 11:30 am - 1:00 pm. She never falls asleep before 3. I have to pick up my older DD at 3, so if she does fall asleep, I have to wake her up. Sometimes I put her down after I pick up DD and she will nap from 3:30 - 5:00 pm (and usually falls asleep pretty quickly). But that seems so late! She gets up at 7:00 am, goes to bed at 8:00 pm. If she doesn't nap, I put her to bed a little early.
Any ideas? She isn't unhappy, isn't crying. I've tried giving her books/toys and giving her nothing. She will talk and sing to her toes! She's standing up, rolling around, standing on her head, etc. Anything but laying down. And if she doesn't nap, she is VERY cranky, so I know she needs it!
