She is bored and mad at you.
Tricksie did for a while but does not anymore.
I have the washable pee pads but I don't find that they work for me, I want to wash them every time she pees on them and when she poops, it covers 3 different areas. I just use them for a base and put the disposable ones on top. The ones I have can be washed about 100 times.
Is your baby crated? Tricksie is only when I leave for a couple of hours.
