Now, I’m a father, and my 17-year-old daughter is starting to gamble too playing slots and even doing some sports betting. I don’t know how to feel, part of me feels oddly proud of what she’s doing.
What does that make me?
You're a good father don't think any less of yourself because there are some fathers that are doing things more worse than allowing their children to start gambling at a young age. You're concerned because you care about your daughter and she should be proud of having you because you won't allow anything to happen to her. My Advice would be to channel that desire she has into something different and maybe when she gets older and want to still be gambling than that's her decision to make. Assuming she isn't doing it in a way that's going to affect her in future but she's being wise about the way she goes about gambling then you don't have to be worried much. Maybe she's interested in making her own money, teach her other means to achieve that.
