My dauhgter in law does not want my help, how can I visit my granddaughter?

I would think the problem probably starts with your son... Have you talked to him about this? The thing about daughter in laws is: They have their own mom to turn to... Unless your son is the one to call you and invite you to special occasions, your visits could be next to nothing...[ Sad but true]... Would it be possible to just stop over to their house for a friendly visit? ... Good luck...
