The hang of walking and opening up doors

Mary Reilly is pretty much walking now. Depends on where and how fast she wants to go she walks. My dad plays chase with her around the house. I don't know why but she seems to walk much more at night. It's been hard because one minute she is in the room and the next she is trying to get up the stairs (thank god I have a one story house!)

I put Mary Reilly in the pack n play (more on the pack n play situation down below) in front of the door. She likes to watch Cooper outside. I noticed she was opening and closing the door. (Notice Cooper in the window-he is very confused and wants to come in) I did catch her opening the door not even in the pack n play. Now it has to remain locked.

The pack n play situation:

I refused to put Mary Reilly in a "play pen" until I found it very difficult to do stuff around the house. She is walking everywhere and I can't keep up with her. She hated it! Pretty much cried the entire time she was in there. I have used this as her crib on several occasions and I think she thinks she is going to sleep. My mom told me I needed to get her used to it since the next baby is not far along. I really didn't want to put it up at my parents house since I have "baby stuff" every where. Now she is fine playing in it. It makes me feel better I have a place for her safe when I have to run upstairs or to the bathroom.
