Our family is LDS (Latter-Day Saint, or Mormon which you can find more about HERE) and we believe in baptism at 8 years old. My twins were recently baptized and I just had to share a very SIMPLE but very UNIQUE gift they received from their primary teacher...
She calls it their "secret code." And all she does is take the child's initials and writes out a unique code, puts it on scrapbook paper and frames it.
In their class, it's a big deal to find out what their special code is going to be. The child can decide to keep it a secret or share it. My twins have theirs displayed in their bedroom as a constant reminder of how they can strive to be better!
