We started out with an Xpen and lined the bottom with pee pads...and the first week or so he would have accidents and then he stopped and was able to hold it more and more. I would come home at lunch and let him out and now he is 8 months and he can hold it until I get home with no potty pads at all. He hasn't had an accident in 3 months! He does still have accidents in the house if we get busy and don't see the signs but we are working on that! He is to the point now where he holds it through the night and very rarely do I have to get up and take him outside...it takes time and patience but I know that hopefully in the next 3 months or so he will be there
