Talk to your MB. Ask her what she has in mind for dealing with the problem of Grandma and if she doesn't have a solution, offer one or two of your own. It sounds like MB and DB want to work with you to make this manageable, so to answer your question, yes, I do think that would be an appropriate idea to mention after hearing out your MB on her own ideas.
