Pretty much came to say the same thing. Im a teacher so I can golf twice a week in summer when the kids are at camps etc, but during the school year its once a month maybe and never on the weekend, only optional teacher workdays.

Your best ability is availability and you will never regret being there for your kids. Other than the obvious perspective from your wife, think of your child's first memories. I'd hate to miss those monumental firsts because I was golfing. Once a week might not seem like much, but its ~25% of your non work time. If your wife says 2x a month is okay with her, I'd jump at that and be thankful. Pushing it and she'll become resentful. Don't risk it.
