I love 4H. Beyond giving kids an opportunity to explore multiple interests under adult mentors, 4H stresses public speaking skills from an early age. In our county, every 4H member, from first-year Cloverbuds to practically-graduated high school seniors, must give a demonstration speech every year. This is Boy #3's first year in 4H, and at the age of 6, he was more than a little nervous at the idea of talking in front of a group of people. But he did it! His "How to Make Nachos" speech was a huge hit.
Interesting side note: While he gave his speech, Boy #2 was at home on the couch with the neighbors, with what we'd later learn was an inflamed appendix. Life!
