I need some advice I moved out of the grandmother house and into my husband mom house for now until we saved up some more money. My grandmother keeps peeing me off bc she thinks she can control me and my daughter for example like today I rescheduled my daughter wic appointment to other week and she calls them and they told her that I rescheduled it and then she texts me y did not let her take me. I mean I am her mom not her but she thinks that I can't even take care of my own daughter
