I have to agree that the schedule change might have thrown him off. I had an xpen for Lex in the beginning to be sure that over night he went potty where he was supposed to and not all over the house. I will only use the piddle pad when it rains I rather keep him on the outside deal. I do leave it at the front door for him in case something comes up and I can't get there to let him out at the correct time but I find if I keep my schedule with his feeding he wont' use it all. Otherwise I get up take him out and tell him to go potty, then bring him in and feed him, I will walk him a few minutes after he eats again and he will go. Then later on my kids will walk him when they get home. I also then feed him at around 5 or so when I get home from work and follow the same procedure I did in the morning. I find that if you want them house broken leaving food around all day doesn't help at all so I schedule his feedings. Judging by your household's schedule I think you can set up a scheduled feeding to help you out.

Good luck and let us know what happens.
