I use this xpen and use 4 panels so it is smaller and then I put 4 pee pads under it to protect the floor and when I put the xpen down a little of the pee pads stick out so the xpen holds them in place and where they 4 meet in the middle I put his crate on top of it (with the gate part off) and he does really well. The first week or so he had accidents but once we got the routine down he has only had maybe 1 or 2 pee accidents...but that was when he was home longer than normal. I would suggest getting one and start leaving him in it and extending the times a little each day until the holidays...expect a few accidents in the beginning...but it won't take long before you baby gets used to it. Mine love sit...he sleeps in his crate at night but does not do well leaving him in it to go anywhere...so we put it in his crate in the xpen and he goes in it to sleep when he wants too...and I put lots of chew toys in the xpen so he can play too

Here is the xpen that I use:

I got the 6 panels and the extra 2 panels to make it bigger to play outside in the summertime...
Good luck!
