I have a 13 month old who we adopted on Valentines day. He is almost completely trained on the washable potty pads. Whenever we get up, first thing, I take him to the pad and keep telling him to go Potty. This usually takes about 3-5 minutes. On the bright side though, the time he is going is getting quicker. Just whenever you see him doing the," I am sniffing out my new spot" just put him on and keep saying the adjective of your choice.
It is going to take some time, but once you get that done, having to crate him will be obsolete. He can have a little more freedom. Best of luck!
And by the way, Welcome to YT!
