I think it is a great idea, it is not a cage at all, no top or door just a large play area to keep the little ones safe. If there is any one who doesn't like the idea have them watch a toddler alone for a couple hours, try to get something done in the house or yard, go to the bathroom etc. with a little one on your lap or hanging on to there leg and we will see how well they agree to something like this. It is not like they are being locked up all day.
