Welcome and congrats she's a cutie pie
I think one of the best investments for anyone owned by a Yorkie is steps. I am not sure if you are going to let her on the furniture which you might say no now and change your mind
But steps are great for them. I have learned not to let Georgie jump much and really he doesn't want to. I would also suggest allowing her to have the run of the kitchen. While your bathroom would work I think the kitchen would give her more room and she would adjust better. Good luck and keep us posted
