My kid plays, started at 7 and looking forward to playing his Sr yr HS next season.
After 10 yrs, I'm still surprised at the number of parents worried about imjuries, who also have never paid for a quality checking clinic.
We found a great local guy that runs top notch clinics of all kinds. My kid was one of the smaller, and slowest skaters when he was little, every team.
We knew he was going to get crushed. So, we started him in checking clinics a full 2 years before he could hit, and kept with it the first 2 years he played full contact.
Went through 3 different org's running clinics, decided the first was the best. He averaged 2 clinics a year. So he had at least 8 clinics, over 4 years, with different instructors.
In HS hockey, any player can get hurt at any time on any play. But we dont go in with any fears as parents. He's still not a big kid, average size at best. He's very strong on his skates. Plays 100% heads up hockey. And for years has known how to both deliver and accept a solid hit. He skates through most stuff, when he goes down, we expect him to bounce right back up.
When he gets blown up, its usually eating a hit to make a play. Everyone around gasps, the wife and I just expect him to pop back up.
Giving them a solid foundation early is the best piece of equipment going! Playing scared just gets kids hurt.
Start early. Before you need it. Then enjoy the next 10 years.
