No doubt it changes your life. Less sleep, less time for your self, basicly your life resolves around your kids lives. The good part about kids if you are trying to start your own business is that it adds a constant to your live. Your business is a wild roller coaster ride but no matter how bad your day was or how big the disappointment your kids are there at the end of the day. It makes you realize on a daily basis that there is more to life than a business a product or a job.
