Linz -- I'm sorry. Could MIL go to adult day care? She probably wouldn't go for that, thouh, huh.
I don't want to say we had a similar thing happen with my MIL but, in a way, we did.
The VERY short version is that there was a huge amount of drama surrounding her move to our city. She totally ruined our holidays. Then she never got her own apartment, which was the original plan, and lived, without even asking me if it was okay, on our couch for 2 months. We did question her competency the whole time she was caring for Maisie. I was very uncomfortable with it, honestly. She was hugely defensive every time we made any suggestions (you know... on how we wanted her to care for OUR baby). She and dh argued constantly. It was awful the whole time. But the cherry on top was that she decided she couldn't handle taking care of Maisie like 2-3 hours a day during the week when hubby was in class (he had several evening classes so I was home to take care of her like 30 minutes after he left for class). My husband had to DROP OUT OF SCHOOL (after he had already paid over $4,000 for the semester!!!!!!!!!!!!!). Then after she moved out of my house, she kept dropping by, almost weekly, sometimes totally unannounced. The last time was a month ago and I couldn't help but act like the biggest b**** ever to her. When I pulled up to my house and saw her car in my driveway, I wanted to turn around and go somewhere else. If not for looking so forward to hanging out with Maisie every evening, I would have. I can't even stand seeing her face anymore and I don't think my mind will ever change.
Oh, and also, the first night she spent on our couch, her cat pissed on it. Did she offer to pay for it? Um, no. To this day (like 8 months later), I still smell cat piss every time I sit down on the couch even though I've cleaned it like 40 times. Did she offer to contribute to the bills or mortgage while she lived with us? Um... no. ugh.
