Can't stand my Husbands family!

I honestly can not stand my husbands family his mother always tries to tell me what to do and how to dress my daughter. She bought my daughter a lead painted crib knowingly! And she will purposely exclude me from pictures! I have never done anything to them I've always been nice no matter how I felt about them. She's mad because I won't let her be in the delivery room when I deliver our son. If I tell her no to something she will go behind my back and ask her son and tell him I told her yes! Does anyone have any advice? My husband somewhat sees what I'm talking about but it's still his mom so he doesn't say anything.
