Anonymous wrote:OP here. Just to clarify, my MIL isn't toxic. She just has her own beliefs and agenda (as we all do). She doesn't belittle or ridicule my husband, our children or myself. She clearly loves us all very much and just has issues with dealing new ways (instead of her old, cultural ways). Her own mother was very controlling, and this dysfunctional relationship still has its lingering repurcussions. MIL will claim she doesn't feel loved if we don't welcome her with open arms, but she never, ever insults us. Life is complicated. This agreement allows me to minimize the impact to my nanny (I'll probably give her Friday's off), and my work week. I'll work on telling her to stop rearranging stuff.
I can't help but to find it bizarre that OP's overriding concern (restated again and again) seems to focus squarely on the nanny and how she will handle the MIL's extended visit. I get it. A good nanny is hard to find. And you don't want to risk losing her. But it seems like your mother-in-law's extended visits impact your family and your routine well beyond the nanny.
