How do I handle my mother in law? I’m just after some advice. My mother in law and I used to get along. Once my daughter was born she started causing fights and being rude in front of people and acting dismissive towards me. Our daughter is 4 months old and she lives only 15 minutes from us and she has only seen her 3 times in her whole life, due to her not making an effort. She continually will start fights with my husband or myself and I’m at my wits end. Need some advice on how to deal with her please.
