Hi, I'm new to pokemon as my youngest son has taken quite a bit of interest in it. We've heard of a pokemon league near where we live and he really wishes to be a part of it. My daughter's friend had informed us of the league but he's also told us that if my son joined he'd be the youngest member there by a few years. He's 7 years old. I'm not sure if it'd be a good idea to let my son join. I'd be more willing if his older brother or sister were willing to stay with him. I've never met the league leader or whoever runs the place. Please, help me on this decision.
