I am the caregiver for my 87 year old mother, who is definitely showing signs of dementia. Her memory is failing and she is forgetting how to do simple things for herself. Today, she gave the sitter a hard time with her bath and the sitter said mama hit her. The sitter wasn't upset and said that she knows it's mama's mind. If mama should hurt someone, am I going to be the one liable for any possible damage?
