To my knowledge I don't think there is an average per say. They shed as they grow, escpecially if its a little one. My 7 yr old maybe sheds 4 times a year, while my smallest 3 year old sheds about 7 to 8 times a year. I am looking at my data on all of these guys and to be honest I can't see anything that is consistent across all of them. Hope it helps.
