Wicked mil of the east

Anyone else have a mil that won't stop trying to destroy the family so she can get the baby ?? Before I was pregnant my mother-in-law wasn't a nice person and tryed make me get mad at her but when I got pregnant she was the sweetest thing in the world now that my baby is born she has tryes to start as much drama as she can telling us shell take the baby and try to get rid of me. She's never and I mean never around but had the nerve to say I need to grow up and take care of my son and clean and cook Funny thing is my house is spotless my son is a happy baby and I cook all the time 😡 she is like the devils daughter right now. Just wondering if anyone is having the same problems?
