Okay, I could cry,

I came here to find answers, but it looks like no one has any!

My 5 year old will only use one pee pad in the laundry room. She's almost perfect (in my house). Bring her anywhere else, it's open season on throw rugs in other people's houses! WE don't have any throws for obvious reasons.
But the real problem is my 7 month old. I started with 3 pads in
other areas of the house and any time I try to get rid of one and narrow it down to the one in the laundry room, she still goes in the area where I took it from. I'm afraid I'll never get rid of all of them, there will be four pads in my house forever. And she goes down the stairs to where she can't go any further because there's a gate, and poops on the bottom stair!

And all of this when I'm not looking!
Maybe if I had a
big house, but the pads are literally within 15 feet of each other. I am concerned I will have to go to crate training. Tonight, she peed on a blanket that was on the floor, then at the front door on the bare floor. I think she was mad because I wasn't home, my husband was with them. I work at home so I am here so much that I think she got spiteful because I left.
I bet Cesar Milan would laugh at the thought of Pee pads, how unnatural!
