In laws not handling my baby properly.

I have 14 month daughter.My mom in law is schizophrenic patient.She doesn't even wash hand after toilet.if i ask to do so before touching my baby she fight with me.She also lie a lot.sh will pee anywhere and wipe using my baby clothes secretly.she behaves too bad with me. I clean her pee and poop but i am treated like maid. My father in law is no less. He once rounded earphone wire around baby neck. We are on third floor, he takes my baby very near to railing to show down garden. He also uses knives, scissors to cut her hair while playing. My baby is walking and is very active. She climbs on chair then of dining.whenever i ask him not to take risk like this his ego gets hurt and he is like i should never instruct him as i am daughter in law. My husband is very supportive. My Father in law always shouts so bad on my husband since childhood that my husband is still scared of him. I did love marriage and they have never accepted me.that was okay.But i can't sacrifice my baby
