Roll Over!!

Haha...Makenna rolled over from her back to her tummy for the first time last night. I put her to bed and like an hour she started crying. I went in to check on her and she was on her tummy and stuck in the corner of her crib. Today...everytime we put her on the floor on her back she rolls over onto her tummy. She gets so frustrated because she wants to crawl but she doesn't know how...its funny!!!
