I set it up in Malakai's room since we got it when the weather was still wet + cold (which it still is most days).
He really liked to play in it and especially when I climbed inside with him. He also enjoyed playing with the velcro door on the front. I was worried that with how rough he was being he'd split the stitches but they held really well!
A couple weeks later he figured out that he could tip it over. So all he wanted to do was run into the sides which got a little scary with him bumping into furniture.
I think if it had weighted down sides or corners that he wouldn't have been able to tip it. I also would like to have stakes for putting it up outside to keep it in place. It may also just be better for him once he's a little older, so for now we put it away. I'm planning on brining it for our camping trip in July to give him a play space out of the wind and sun.
