It’s a kid showing you that they feel affection for you. Depending on the age of the kid, it could be as simple as: adult woman = a mom = happy Mother’s Day.

I am not trans, so I can’t speak from experience about how you should feel, but my outside opinion is that you should try to enjoy it for what it is—a female experience, a nice little gesture, and a potential for bonding. You aren’t the first woman to have their boyfriend’s child get a little attached, and you definitely won’t be the last. If this were my child and my girlfriend, I’d want to discuss things together so we can navigate the growing bond with the child in a way that is healthy for everyone.

I hope this story has a happy ending. Adult/child mentor relationships don’t have to always come from a spouse, and they can be really great for both the child and the adult when handled well.
