For example, I will not host her at home if my husband is not also home. So, for example, DH is not allowed to invite her over for dinner if he isn't home from work in time to cook and eat the dinner with us. Anytime DH complains that we "haven't had my mom over," I just say, "just pick a date that you're able to come home early enough to cook the dinner and that's fine with me." Lo and behold, she has not been over since.
So I would say flat out that they are not allowed to come over while you are working at home, it is too disruptive.
If they live near you, you should try to make things happen at THEIR home. I.e. she can cook her huge meals at their apartment and you guys come over to eat.
Do you have an older child that she can help with school drop off/pick up? Try to figure out things they are good at where they can help.
Maybe send over one child to A-Ma's (i'm guessing she's Asian) home for 1-2 hours in the middle of the day to give the nanny a break.
This.
