Nap Time?

This is supposed to be the end of Brianna's afternoon nap. She normally naps from 1:30 to 3. I starting rocking her about 1:30 and she fell asleep after about 10 minutes. When I went to put her down in her crib, she woke up. She has been doing this more frequently but has started laying back down and going back to sleep after a few minutes. So, when she woke up this afternoon, I told her to have sweet dreams and that I would check on her shortly. So after 5 minutes, she was quiet so I went and peeked in on her. She was standing up in her crib looking towards the door! I laid her back down. I checked on her again in ten minutes (we use the Ferber technique) and she was standing playing with her mobile! After fifteen minutes, she was playing with the woodwork on her crib! After 20 minutes, she was laying down and playing with the wall. It has almost reached the 25 minute mark, and she has just got quiet...I wonder what I am going to find! Here's hoping she went to sleep!
