This is going to be long...
Cerise has been using the potty pads accurately for 10 months now, but suddenly she has decided to start peeing under the chairs in the living room...2 and 3 feet away from her potty pad area.
I got new carpet at the beginning of November and placed a yoga mat cut in half (both pieces) to make a large square underneath for extra protection. I use four potty pads and make a large area for her. She has been using the pads faithfully until about a week ago. I noticed every day when I come home from work her pads were dry
I take her out every morning when we get up at 6:30am and as soon as I come home around 4:50pm and then once before we go to bed at 9:00pm. This has worked so well until now
Cerise is 17 months old and I have noticed a few temper tantrums lately and the need for extra attention. She travels most places with me (except the grocery store) and when I go out without taking her for the ride I come home to something shredded
Today when I came home I smelled urine for the first time and She saw my face and ran and hid under the chaise lounge. She new I was upset and I know she knew why. I pulled her out and put her in time out (her play pen) instead of taking her out. There was no urgent need because the carpet had a wet warm spot

I got on the carpet and scrubbed and cleaned like a mad woman.
Okay YT Aunties and Uncles. Does any experts have any suggestions on how I can resolve this?
