The financial advisor is going to monitor her investment account periodically and will let me know about future transfers. And, I have my mom's bank account login.
Also, once I calm down a bit I will talk to my sister & brother directly...I'm sure that will not go well, just like Gizmo's experience but I have to make it clear to them that Bank of Mom needs to not be an option. Hopefully they'll react like responsible adults, but if not...I won't miss them.
Anyway sorry for derailing a bit, OP, but at least you know you're not the only one with this problem. Savers are just too easy to victimize.
