I signed my son (2 years old) up for a learn-to-skate program through a local youth hockey team and had a couple questions. 1) Obviously he'll need skates and a helmet, but what other equipment is required/recommended? 2) How much will I be expected to participate in this kind of program, do I need to get skates that fit? Is it an issue at this age if my skating is questionable at best (I realize I'll eventually have to take lessons in order to help out at practices when he gets bigger). Thanks in advance.
