I'd offer a different perspective than others here: it really doesn't matter how many kids you have, nor how old they are.
If you ignore the initial 6-12 months (once they get into a regular sleep schedule), the impact for the parents for the rest of the time between 1 to 17 yrs-old is pretty much the same. The dynamics will change as they get older, but you'll still be spending considerable time on the various family activities: playing with them, having breakfast/lunch/dinner, going to the park, teaching new things, commuting to/from school, attending their friends' birthdays on weekends, helping with schoolwork, maybe teaching them how to code :), etc.
On top of that, you'll also need to find time for you and your partner, family, friends, hobbies, reading, etc. Add a full time job, a school that starts starting early morning, a fixed annual vacation calendar, and you pretty much don't have many hours left in the day.
Sure, some activities can be shared with your partner, and some can be delegated (family member, nanny), but the conclusion is still the same: time management becomes a lot more critical once you have kids.
Which then leads me to sleep. In order to dedicate enough time to a restful night of sleep, you'll need to prioritize things much more effectively, so you don't end cutting corners, and changing drastically your sleep patterns.
