My husband and I quit full time jobs to build our second startup, whilst also having two kids to raise (8 and 6 years old). I don't feel like it's hard at all. I'm pretty disciplined, so I guess that helps. Perhaps I also see the world differently. But overall we're happier, we spend more time with our kids than when we were in jobs, and life is great.

I would also point out that the 'family business' is nothing new. Sure it may be somewhat different when you're building a business to scale, but there are plenty of examples of family businesses where the parents work huge hours and are also raising kids. Heaps of examples come to mind where the parents are literally managing the store 6 or 7 days a week, and somehow looking after children as well.

If you see 'having a family' as a barrier then it will be a barrier. Personally, raising kids and building a startup has never been an 'either/or' choice. In fact, since I love my kids and also love building a company... nothing could be better than having a life where I get to do both.
