Do you have any pics of him with his hair not fluffed up? Was it cold and windy that day? If so then I think he would look a little younger than he does in those 3 pics. He would definitely look more like a 3 yr old.
Don't have any other good zoom lens camera picks of him...only cheap trail cam pics. It was cool (upper 40's) and yes windy (15+) that morning.
