My kids started on a kitty kat at age 2, then a 120 at age 4. My son moved up to an Indy Lite 340 in the spring of age 7, riding it in Golden B.C. Next winter he'll be 10, and he's ready for a bigger sled with a deeper lug track. Today, my eight year old took the 340 for a spin and she likes it! No surprise there. Neither are big for their age, but they ride year round on atv's or dirtbikes as well.
Supervision, and proper gear are key to kids riding safely. Get them a chest protector in addition to a helmet that fits. I feel the sooner they start, on a sled sized for them, the better. Have fun, they sure do!!
This was Revelstoke powder rippin' at age 7.
