It's probably my first negative comment on HN, but as a new father of a 6 months son, and a co-founder of a startup, this just irritates me. I spend 2-3 days per week working from home, being able to take a lunch break with my wife, or change nappies for my son or feed him in the morning before hacking away. I catch up later at night when he sleeps, but generally manage my time well between those two. I'm not a perfect father and not the most successful entrepreneur, but these are the choices I made and the challenges I face. I think it's important for my son that I'm going to be around, but also that he has a father that is proud of his work and enjoys what he does.
