Sounds like you're off to a great start! We went from potty pads to outside as well so I'll try to help.
We started off by going out first thing in the morning, last night before bed, and every 2 hours in between. Now that they're trained we go out every 4 (sometimes 5) hours. I would take them out, wait until they pottied, and praise and treat. It helps to find something they
REALLY like. This encourages them.
We used cheese and the only time they got cheese was when they pottied. Once they got the hang of it, we went out every 3 hours and now every 4.
Feel free to PM me if you have any questions!
