I’m sorry, but I find all of these obstacles as insufficient. Once there is a grandchild, nothing can keep a grandmother away but distance. This I know from experience. My folks live 3 hours away and contact is limited to phone calls and trips made to visit them. My mother-in-law lives across town, a trip of 30 minutes or less, and physical visits are on average of 2 to 3 times a week. Good thing I get along with her.
