When to Start
Discipline, undeniably one of the most important elements of parenting, is also among the most misunderstood, difficult, and anxiety provoking.

Discipline is less about playing the tough cop and more about playing the kindly teacher. Here's an approximate time line for introducing routines, rules, and general good behavior.
