My husband wants his pregnant sister to move into our house because she’s having problems with her living situation. We have three daughters, and each of them has her own bedroom. My husband and I share our bedroom as a couple, so everyone already has their own space. I agreed to let his sister stay temporarily because I didn’t want her struggling during her pregnancy. But a few days after she arrived, she started suggesting how we should rearrange the bedrooms to accommodate her and her son. I don’t know his exact age, but I’m sure he’s Gen Z.
