So with a pretty crazy household of 5 year old triplets I wanted a super safe and fun area for our new babies to be able to run around an play in. After doing lots of research I found this great "pen" on Amazon... I love it because it has the zip closure, is easy to fold to put away and is a really great size. We haven't had our girls super long so we have only let them explore in here a few times. I'm really looking forward to coming up with and finding new things to put in here for them!
