Do time outs work?

What the evidence says

Time-out has a long track record. It's a core part of established, evidence-based parent training programs, and reviews describe it as effective for reducing defiance and aggression when it's used the way it was designed: predictably, calmly, briefly, and without talking, warnings, or access to toys during the break. The catch is that most parents don't use it this way.

A survey of parents found that the vast majority who used time-out made at least one mistake, such as giving several warnings, chatting with the child mid-timeout, or letting them keep a toy or book. Parents who followed the steps correctly were far more likely to find it effective. Canadian guidance frames time-out as one tool among several, to be used after trying things like connecting with your child, naming their feelings, and redirecting behaviour, and generally not before age 3.

Canadian paediatric commentary also notes that time-out's role as a routine, first-line strategy is being actively re-examined, partly over worries about attachment, especially for kids with a tough history, though a recent Australian study found that when done properly, time-out was linked to better child mental health and attachment, not worse. Bottom line: time-out isn't a fix on its own, and how you do it matters as much as whether you do it at all.
