I spent many of my younger years hanging at my dad's hip as he worked on anything from fixing the furnace, making new air runs, fixing door knobs, working on his motorcycle. I learned what tools were what, and after a while I could anticipate what the next tool he would need was, rather than him having to ask.
I spent 6th grade to 9th grade sitting in the garage of my Step Dad's as he worked on his 70 Chevelle, and 69 El Camino with a big block. Fetching tools and asking about what he was doing, helping put new springs in, working on carbs, changing out distributors, wiring up tachometers.
Spent the summer of 9th grade at my dads with a 1965 corvair my step dad gave me, hand sanding all the bad paint off it, repairing holes in the steel with fiberglass mesh. Sticking blocks in the springs to fit 14" uni-lug dish aluminum wheels. Later we did the clutch job.
A couple years ago me and my brother went over to Dad's and swapped the clutch out for his car in the dirt driveway in about 1/2 of a day.
Point is. Kids may bother you when they are young, but if you stick with it, they'll turn into real help as they get older, and eventually you won't have to do it anymore, they will do it for you.
