I put the disposables on top of the reclaimed pad for a while, then just stopped when I ran out of them. The girls did great, though my bedroom carpet was fair game until we ripped it out

Now they rarely go off of the pads
Oh, and I tried that spray too, it did NOTHING

It's just going to take time for them to get the hang of it, but using the disposables on top seemed to do the trick for my girlies
