Mommy gets around with a walker, she has it in her mind that she has to go to the bathroom 10-15 times a day. Most of the time she doesn't have to go but sits there and strains. When she does go, she then tries to empty the potty chair that my brother has put in her room. She will also, if she has pooped, take it out and try to wrap it up. She doesn‘t want my brother to know she's gone to the bathroom now...this wasn't an issue a few months ago. She has also started to try to wash her hands with the urine. My brother is constantly wiping things down and cleaning her up. What can we do? (She lives with him and I'm worried about him now) Any thoughts?
