Mothers-in-law please help me understand!

My husbands mother is strange to me. I understand why she doesn’t want me around when she hangs out with my kids. I’m not her kid and she wants to see her grandkids.... I get it. I’m fine with that. She can have them anytime she wants and do whatever she wants with them.What I don’t understand is why she is so adamant about giving my kids baths. It bothers me because her house is filthy. She “cleans” the bathtub before she puts them in and then puts them in with whatever leftover chemicals she’s used. (Not a huge deal... but I’m upset so every single small thing bothers me)And then I have to hear about it. My boy is 9 months and doesn’t like to be wet. So I have to hear her question me as a parent as to why he doesn’t like to be wet....... because he’s baby. He doesn’t have to like it but he does have to take a bath. He will eventually get used to it.My girl is just over 2. She HATES getting in the bathtub but then enjoys herself and doesn’t want to get back out. MIL will negotiate with a 2 year old. She BEGS her to get in the bath and when my kid says no no no for 30 minutes MIL will give up and let her have her way. Again; she doesn’t have to like getting in the tub but she has to take a bath. Now I have to deal with terrible twos that got her way at mawmaw’s and came home to mom that makes her do it anyway.My kids are soooooo winey and will not follow directions when they come home from MIL’s house. That’s the part that I don’t have to like, but I have to let them have a relationship.I need help understanding this woman. I need perspective. I didn’t have grandparents growing up. I love that my kids have this relationship and that they are spoiled by them. via /r/Parenting https://ift.tt/2FLbwv3
