MIL always confront baby sitter

My mother-in-law always thinks there's a problem with my child's babysitter. I've already changed babysitters twice because they kept arguing with my mother-in-law. Either they weren't clean enough, or they were too close to my child. The problem is, my mother-in-law is confrontational and likes to yell. None of the babysitters can handle it. I talked to my husband. He spoke to his mother, but she got mad and said, 'That's because I love your child!!! That's my grandchild!!!' I don't know anymore. I'm so stressed. Now I have to find another babysitter because I really need one. I have to work, and it's impossible to leave my child with just the grandmother. P.S. She also doesn't allow me to put my child in daycare. Ugh.
