MIL KEEPS OVERSTIMULATING ME IN MY OWN HOME

Help my husbands mother moved in with us in June. I would rather her not live here but she has nowhere else to go. She helps watch my kids during the day which I am grateful for but she is so damn annoying. She loves music and I mean so much she is constantly humming, singing, drumming, dancing etc. She pretty much is never quiet. It makes my children even more crazy and it drives me nuts. I’ve talked to her about it multiple times and she stops in the moment but then does it again and again later on. I keep having to tell her to stop and it is frustrating. I told my husband how annoying it is but since he grew up with her he thinks her behavior is normal vs in my house things were more quiet and less intense 😩 l am not expecting everyone to just sit silently on the couch but having a loud band dance part all day is frustrating. It’s honestly affecting my mental health. She also has no boundaries meaning she won’t give me and my husband alone time…again I’ve talked to her about it. She honestly just seems not self aware.
