As a retired psychologist, I would emphasise that the primary aim of discipline is not punishment but learning. For very young children words alone may not always communicate the seriousness of a dangerous or socially disruptive behaviour.

In such circumstances, the carefully controlled use of an aversive consequence – such as a light slap on the back of the leg – can serve a valuable role. Behavioural psychology demonstrates that immediate, proportionate consequences can interrupt harmful actions and provide a clear boundary that the child can understand. Unlike protracted lectures, which exceed a toddler’s cognitive grasp, a swift physical signal can prevent escalation and, importantly, avert greater dangers.

This is not to advocate harshness. Discipline is most effective when coupled with warmth, predictability, and love. But within that framework, the occasional smack can provide clarity at moments when reasoning is impossible, and when hesitation could risk harm or foster entrenched disobedience. Used judiciously, it is a tool that reinforces parental authority while safeguarding the child’s wellbeing.
