I have a bit of the same situation too. My first is a girl and Im obsessed with being a girl mom so I was a bit disappointed to find out we’re having a boy. They’ll be 17 months apart. My husband and his brother were both small town hell-raisers (their term). While I’m scared of my husbands expectations for this little boy, I’m certain they were what they were because of the way their parents raised them. Very don’t ask, don’t tell kind of people and still are. I don’t think being bad or risky is genetic and I think it’s important to sit down with your partner and talk about expectations for parenting. I’m needing to do this myself too.
Only some things are genetic I think a lot of how a kid acts comes from how they are raised/who they are around.
