my son at 5 was wearing a 3t and had a size 4 shoe. he's 20 now and is 5-1/2" and 112#. I know where you're coming from. i was a daredevil.This is what i learned b4 entering kindergarden... i used to jump off the garage roof at age 4. tried plying paratrooper at about the same time with a sheet. Don't try it, it doesn't work. Neither does the Mary poppins thing with an umbrella . i'd mix chemials together, bleach, ammonia, comet, only God knows how i didn't blow myself up. Lit fires with a magnifying glass. did the swing thing too, i figured if i got it up high enough, i could go around in circles. I sympathize with you. I now know how scary kids can be, but i lived thru it. I didn't help i hadan older bro. telling me what to do. the funnest thing i can remember, waas tying a clothsline to the top of one tree and the other end to the bottom a fence and taking towels to put over the line, hold both ends and slide down the rope. that was wild.
