Ok Now I know that many of you guys have ex pens, My question is how in the world do you keep them from jumping out? Bella is only 12 weeks old. and her pen is like 2 1/2 feet tall and she is soooo tiny, but she is jumping right the heck out..
..she figured this out this morning, and now there is no containing her. so how do you keep your babies from doing this???? HELP.
