Query: Not very sturdy

I bought this for my 2 and 1/2 year old this chirstmas. I was slightly disapointed. It wasn't as big as I thought it would be, and it has a hard time standing up on it's own. You have to prop the sides out for it to stay. Anyone that goes thought the door will knock it over, which is frustrating for a 2 year old. I had to set it up over and over. If my 6 year old tried to get in as well to play, it tipped over or there wasn't enought room. If I had known how flimsy it was, I would of spent the extra 10 dollars to get a framed tent.
