Whether you want them to or not, little boys (and sometimes even little girls) are going to be interested in weapons and violence. For some reason it just happens to be in our nature to enjoy particularly violent activities. When your child starts to build guns out of his lego sets or wants to run around playing cops and robbers or cowboys and Indians with his play mates outside it might be time to sit them down and talk to them about getting into archery.
Archery is a time honored martial arts practice that is fun to participate in and it will also aid in the patience building and concentration building processes for your child. If you start your children out early by channeling that new interest for violence into something positive they will be better off in their adult lives. It is important to catch negative behaviors early and turn them into positive behaviors, that way they will use their time wisely and learn new skills rather than frivolously wasting their childhood out there playing make believe.
