Family disapproves of choice to homeschool
We have a 5 year old and have made the decision that I will be homeschooling her this fall. I knew that this wouldn't make some members of our family happy, but I didn't think they would be so downright rude about it. My MIL keeps asking about plans for school, hoping we will change our mind. Yesterday after I said yet again that is the plan she made a loud "uuuugh" noise and said "oh, I was really hoping she'd go to school". It's getting very frustrating. My sister also has made her disapproval known but I don't see her often so that's easier to deal with.
For context, the schools in my state are okay but not great. More than half of kids can't read or do math on grade level. Our older son is in high school and has had a lot of terrible experiences (fighting and vaping on the bus, kids cussing out teachers with no consequences, etc.) I have a bachelor's degree and also did 2 years of graduate school for teaching before deciding it wasn't my path. Not that that should really matter because it's our decision either way!
My MIL worked at public schools for decades and I understand that she thinks they're great. I also am incredibly grateful that she is such an involved grandparent and does so much to help our family out. But I don't want to continually hold my breath around her waiting for the next lecture. I have no interest in persuading her to agree with our choice, just to accept it! My husband has learned to just sort of ignore her rants and shrug them off, he doesn't want to confront her about it (neither do I!)
Any advice?
