To show possession in this sentence, we need to add an apostrophe and the letter "s" after the word "children". Here's how you can write it:

"The honesty of children is refreshing." becomes "Children's honesty is refreshing."

By adding the apostrophe and "s", we indicate that the honesty belongs to the children. This is a common way to show possession in English.
