I agree with whoever told you to keep her on a leash all the time and attached to you. Best way is to loop the handle end through your belt loop and then clip onto her. That way you are much more conscience of her being out of her kennel, than just letting her walk around herself and every 30 seconds be wondering where she went. She is far too young to be given that much free space already. When you absolutely cannot watch her, put her in her secured area. Or always keep her leashed. Only take her off the leash when you are playing or training. I would say bout 5 or 6 months is when you can start to see potty training progress and start to give more freedom. Even in an apt, you need to restrict her space. Yorkies are so small, they will go across the room and think it's far away enough and make that their bathroom spot. You don't want her to start making that habit now. Ever actually.
