Aww, he is only 2 months older than mine!
As for sheding, it really depends on how long the coat is and how often you groom. If you're out everyday brushing him down, that helps alot. Also...you could start blanketing him near the end of winter and that helps get rid of it quicker.
Blanketing doesn't stop my horses hair from growing! I could have a heavyweight on at the beginning of winter and her hair would STILL grow, she's so weird :P So I don't even bother until it's below 0, it's January and she hasn't had it on full time yet.
