First welcome to Yorkietalk!
Second, congrats on your baby! Can't wait to see pictures.
. When I got Rosie she was 6 months old and had been going outside to potty. I tried puppy pads but nothing worked for me. Then I got Mikki. Mikki is both pad trained and outside trained. Once Rosie saw Mikki using the pad, she will use it now too. She don't use it all the time. Just in emergencies!
. I wish I could give you some training advice. But I really don't know how to get them to go pad only. Good luck!
