Let your little siblings see you mess up and recover. That teaches them more than seeing you never mess up.

A younger kid who only sees you succeed learns that mistakes are shameful, because they never get to see what happens after one. Watching you get something wrong and keep going teaches the part nobody can explain in words: that failure is an event, not a verdict. The recovery is the lesson, and it needs an audience.

Next time you flunk a test or lose a game, say so at home instead of hiding it, then let them see the next attempt. Keep the tone ordinary rather than dramatic. You are showing them the pace of a normal setback, which they will copy for years.
