How do I respond to my mom who keeps saying negative things about my sister?

Chances are that the problem is mostly your mother and your sister is having to tolerate a good bit. If your mother is still of sound mind, I hope you will take up for your sister. It is difficult for two adults to be forced together like this and they probably do get on each others' nerves. Your sister is giving a lot, though, so doesn't need to be talked bad about unless she is really doing something wrong.

How is your sister doing? Maybe it is time for other living situation for mom - like an assisted living. Then sister can go back to being a loving daughter vs the battered caregiver.

Redirect your mom when she begins complaining about your sister. Just change the subject. It happens when you're in the car? "Look mom, they're putting in a new shopping center. I wonder what kind of stores they'll have." Or, "It's such a beautiful day why don't we take the long way home?"

Just redirect her as much as you can. Don't engage in a conversation where your mom is being critical about your sister. The main caregiver often gets the brunt of the dissatisfaction from an elderly parent. If you and your sister switched roles your mom would probably being saying the same things about you to your sister.

Dear TYYoung,

I'm sorry you have to hear your mom being negative about your sister. I'm sure your sister is under a lot of stress from caring for her daily. Because your mom is so negative, have you asked her about moving out? Will she consider assisted living? A nursing home? Or hiring a caregiver?

My dad was also very negative after his stroke. I feel there was some brain damage after the stroke and maybe this affected his personality. They also say depression is also very common after stroke. I know its not easy on your mom. Maybe she might benefit from going to a seniors centre during the day and getting more company.

And for yourself I would consider talking with a family therapist or counsellor. I know you are doing your best too, but hearing all this negative talk can wear anyone down.
