I am still not sure about this whole baby sister thing. She whines, eats, and poops! She is a fiesty little something too! I can't play with her yet because I am really big and I get really excited when she is down at my level. I do keep my eye on her every second of the day though. I get in trouble a lot because I like to go up to her room when she is sleeping and wake her up! I can't wait until I can play with her.
