I have one in my living room for my 13 month old granddaughter. It's funny that she will go into it for me...but if either of her parents put her in there....screaming. I guess she doesn't want to lose the battle with her grandma.
The playpen that my son and his wife have is just a huge toybox. They put her stuff in there for storage. I'd prefer that they just take it down and use the toybox that I bought them to put her stuff away in....but, I'm just the grandma and it is just my family room that they are stuffing with all of their stuff. ( they had to move in with us)
