The more you have, the easier it gets.
Just one? Daddy's little princess. Nothing to do all day but manipulate you. You do everything in the world to keep them from the slightest harm or discomfort. She says, "daddy, I have no clean clothes to wear and I want to go play with my friends," and you feel like a shitty parent for letting that happen and you put laundry in right away.
Two? Sometimes double the work, but when one of them is being a little shit, you can tell the other one "why can't you be more like $sibling." They have competition, so they have incentive to please you. Younger one tries to manipulate you, but they use the same trick the older one did and you've seen it before.
By the time you have 8, the older ones are taking care of the younger ones in exchange for the right to use the car next Saturday. You see the youngest pick up a dirty pacifier off the ground, let the dog lick it, then put it in their mouth. And you just don't care. Number 6 complains about having no clean clothes and you say, "well why the hell did you let that happen? 5! Hey 5! Get over here. It was your turn to do laundry, why didn't you do it?"
Who has the TIME to play hockey with 8 kids.
Makes it even easier. That's 4v4, man! Toss them some gear. Tell them to be home in time for dinner.
(and obviously, this has all been a lie. It does not get easier, your standards just get lower.)
