How often must I visit my mother at the assisted living? (I'm tired of her complaints & criticism).

Given your mom's negativity, visit as often as it takes to determine her needs are being met. More often than that just reinforces the habit of complaining. When I show up at Mom's MC, all she sees is a receptacle for her grievances. I visit once a month or so (unannounced to MC) to make sure all is well and do what I can for her, but that's about all I can take.

There are no musts. You do what is right for you. Mom may even have an easier transition if you do not see her as often. The facility will figure it out, they have seen everything. They will contact you, if needed.

I visit my father once a month. That is all I can take. Start cutting back to once every other week. If she gets nasty make it once every three weeks. What people forget is that she is in assisted living. Her needs are being met so you don't have to be there for her. You go because you WANT to go. And if you don't want to go...well....

Once a week or less. If she’s not in a good mood the day you visit, then leave. That’s what I did. You are not obligated to listen and be responsible for that stuff. It really ever ends. You can’t fix it. Just leave. It’s about all you can do. It’s what I did and she never even remembered I was there.
