Should I let MIL change diapers?

So MIL lives with my husband and I. She has been changing my 6 month olds diapers since he was born. At first I had no problems but now I am starting to feel weird about it.She always changed the diapers of BILs kids and him and his wife has no problem with it. Every time she goes to their house (they have a 2 year old and a couple older kids) she changes their babies and checks them because supposedly they don't change the babies often and they always have dirty diapers when she comes over there.Anyway every time we hand MIL my baby she will check him for pee or poop even if I might have just changed him. If he is crying she will yell from her room "check the diaper!" If my baby is just playing contentedly she will check him. I never go too long without changing my baby and he rarely gets rashesI just let her change him but the thing is I cloth diaper and she never uses them! I only use disposables when all the cloth ones are dirty and I haven't gotten the chance to clean them. I keep the cloth diapers right there and hide the disposables away. But she will go out of her way to grab the disposables even if I always tell her to use the reusable ones! She always complains that they are too hot for him.I Anyway today particularly annoyed me a lot. I change and feed the baby. Then my husband takes the baby to his mom so that we can eat lunch. She comes back with the baby 15-20 minutes later and askes in Spanish to my husband (since they are Mexican) about the diaper. I reply instead of my husband that I just changed him and he is good. She completely ignores me and procedes to start changing him complaining once again how warm it is! I ask her what happened, did he poop? And she told me no, "it smells like pee" and she switches to the disposables again.I go over and check the diaper she took off and there was very little pee in the diaper! She changed his diaper for no reason. I told my husband and he responded like he usually does when I have concerns about MIL. He tells me it's no big deal. He never sets boundaries with her at all, even when I need privacy and she is violating it.I'm thinking about telling her myself to only change him with my permission from now on. BIL and his wife may have no problem with her changing their babies, but I'm starting to think more boundries are needed. What do you guys think? via /r/Parenting https://ift.tt/2PAFDgF
