If you think that counting 1,2,3 as a warning to your child is just a silly act, well, it is actually way more effective. Warning them by counting 1-2-3 will make them be aware how annoying and unacceptable their behavior. If he/she still doesn’t comply with the warning, then you may start using a firm voice and eye contact to show your disappointment with them.The agreed consequence would do after the count of three.
