Verbal warnings must have a consequence if it is to be effective. I have heard parents stretch a three count out to ten or more beats by saying two and a half, two and three quarters, etc. This teaches the child that parents are not to be taken seriously and that they have no real consequences to deliver. And, it should be firmly enforced after the warnings have been given. A few minutes in the time-out chair or an extra chore should do the trick to show you mean business.
Verbal warnings require that parents also provide verbal praise for positive behaviors.
True behavioral change occurs when there is a balance between punishments and rewards. Parents should give verbal praise for any behavior other than the one they are warning against. Great job, Thank you, or I appreciate your help for each and every effort at positive behavior. If done enough, parents might even find they don t need to give a warning. Verbal warnings can be given without any words at all.
