Good job! I remember those days. My older son went all the way to black belt in karate and is a red belt in taekwondo. He loves martial arts. It's a great activity for kids.
Congratulations! I remember those days. My son started at the age of 7 and earned his Jr. and Adult Black Belt. I also decided to take classes while my son studied and earn my Black Belt as well. It taught us both a lot and was very beneficial. Good luck on his journey!
