I know what you are talking about. You can take them outside also. So handy when you can't watch them all the time. Back in the 60"s we had what was called a play pen. Sounds funny but it came in real handy when you had to run down to the basement to take clothes from washer and put in the dryer. We had a pot belly stove in the basement that kept the house warn all winter. I never would have been able to put him down for fear of him burning himself. I also had a gate that I would put in the kitchen door way. He could walk around and play with pots and pans while I did dishes and cooked. Better to be safe then sorry.
