Exactly. Good discipline isn’t about spanking. It’s about responding promptly to misbehavior. It’s about getting off the couch.
I can count the number of times I’ve spanked my kids on the fingers of one hand. In our household the only offense that merits a thwack is gross insubordination … ignoring a direct order from a parent, acting sassy, that sort of thing. As a result of their infrequency, the spankings my kids have received cast a very long shadow. They still speak in reverent horror of “the time Daddy spanked us for disobeying at bathtime” and that was one smack to the bottom apiece over a year ago.
All other offenses, even ones where they’ve unintentionally endangered themselves, are dealt with either by “speaking sharply” or time out. A good scolding is particularly effective against toddlers – they just don’t have the emotional reserves to maintain defiance in the face of stern parental disapproval.
The key, though, is “getting off the couch”. You have to respond swiftly and decisively to challenges to authority. Insubordination is a learned behavior. It’s what you get when you’re inconsistent or unjust in your discipline, and it’s what you get when you get in the habit of saying “no” without backing it up with real punishment.
