Two year olds think cleaning is fun. They decide that popcorn is better for breakfast than cereal with the second and fourth ingredient being sugar. They choose "treats" consisting of few calories, or worse yet, decide yogurt is better than pudding. Two year olds want to help do everything, cook, paint walls, fold laundry, make beds... They remind you to make coffee in the morning. They keep you in their routine.
What do we do to them that, by the time they reach sixteen they no longer want to eat healthy, they refuse to wake up before noon, escape the "jail" before they do their chores and only remind you of their routine after you've managed to forget about them somehow?
Hey! At least at sixteen, we're not responsible for changing their diapers and wiping their butts. You win some, you lose some.
