But sarcasm delivered in a warm joking way is a great way to deflect embarrassment. Let's say Josh comes downstairs, ready for school, without realizing that he still has his pajama shirt on. Next week, I bet all the fourth graders will be wearing their pj's to school. You can model the use of kind sarcasm by applying it to your own mistakes. By teaching children to laugh and not get upset at their foibles, you'll help them realize that some mistakes can be funny and should not be taken seriously.
Mistakes are part of life.
So is criticism. Help your child to handle them both.
