It is not bribery at all. It is just the natural order of things. If a child is named for someone you naturally talk about that person to that child. If you have something that belonged to that person, your natural inclination is to give it to that child because it would have some meaning to that particular child, while it would hold little meaning to a child who did not feel the connection. How is that a bribe?
When I gave my daughter something that was her grandmother for whom she is named after it had some value to her and she appreciated the history of the piece, more so than something of another family member. She wore it with a different sense of pride.
