This could be a tricky question. Yes the brides family knows she's getting married, is very supportive of this choice, likes her husband to be and his family. When getting married its a crazy time for the bride, should she have to call her mother and grandmother and ask them personally for assistance or to talk about the wedding? I would call my daughter/granddaughter. I think its a part of the excitement getting them excited, talking about wedding details, asking her what she is thinking or has figured out.
