I definitely think you should train your new baby to go outside if that's what you want. I've never used the pads, all of my babies have been trained to go outside. I would recommend crate training, you'll get the fastest results because the repetitiveness really helps them to learn quickly. As far as your babies currently using the pads, there was another person on here who decided to transition from pads to outside and did what was recommended above, start with the pads next to the door and gradually move them outside to teach them the new rules and it seemed to work quite well. If you have questions on crate training you may want to do a search on this site and I think you'll find lots of info. Good luck
