If you praise your child for things that are not praiseworthy you set them up for false impressions of accomplishment.
Praising behavior that is not worthy of praise is disingenuous- it is flattery.
Flattery makes praise for actual accomplishments seem hallow.
It sets a precedence that every action should receive applause, no matter how insignificant.
I do not mean that praise should be stiffled. On the contrary, genuine praise should be given liberally to children, and it should focus on accomplishments and positive character traits.
Flattery: A child is refusing to participate in therapy and the mother says “You are doing a nice job of sitting quietly.”
Praise: A child increases their accuracy on a therapy task from 40% to 65% accuracy. The mother says “That was great work! Your practice is paying off. You are getting better every week!”
