"where's daddy" problem is rarely an issue for entrepreneurs.

kids are very good at adapting to their environment as long as their environment is stable and predictable. for example if you spend with your kids whole their life only 5 minutes a day, they perceive it as normal and wouldn't expect it any other way because "that's how daddy always used to be"

the key for entrepreneur with kids is to deliver consistency no matter what that consistency is. follow my advice and you will be happy entrepreneur.
