I considered Bailey potty trained in 2 mos. (when she was 4 1/2 mos old) - at that time she was ringing the bell consistently so I picked up the blankets off the family room floor and let her go into the kitchen as well as the family room.
For awhile, we kept the dining room blocked off because we don't "live" in there. Gradually we let her run the house - but she pretty much just stays in the kitchen and family room with us - all the baby gates are put up!
I bought a spot-bot for those occasional accidents. Truth be told - I've only used it a handful of times due to potty accidents. Unfortunately, I've had to use it a few times for barf accidents, too. Its a great machine and highly recommended!!!
While at work during the day - I keep her in an ex-pen with a pee-pad in a litter box. Its just a safe place for her and she can either nap or look out the window and watch the birds and rabbits.
