I dont potty until there at least 6months its to stressful on the baby and me.
Up until then put baby in bathroom or crate with wee wee pads after she goes take her out to play. Puppys go 20 times a day you dont want to scold all day, there also creatures of habbit so by then they will automaticly go on pad then if you like take them out to train when your not around they go on pads and no mistakes. ps make sure you have urine remover if theres urine on your carpet dogs will try to go there. PS use metal cage its cooler and they still can interact with you.
