TMI, Lady
All grandmas love their grandchildren very much, so it makes sense they would want to know everything they can about them. However, asking in what positing they were conceived is strictly inappropriate. Why would she even want to know that? It’s so private and intimate.

We don’t mean to sound like prudes, but if you ask us, what happens in the bedroom should stay in the bedroom. You can share some details with your friends, but only if you feel comfortable with that. We find it hard to believe anyone would feel comfortable discussing such matters with their in-laws.
