We are lucky in the fact that we can do a lot of the work ourselves. DH knows plumbing, electrical, rough framing. drywall, tiling, etc. We could probably build a house by ourselves, except for the county requiring certified professionals to do everything in order to pass inspections. I trust his work over some of the "Pros" out there nowadays. He has fixed so much on our current house that the pros did half-assed. Only one valve in the entire water system - and that was right after the pressure tank. In order to pull the toilet to paint the bathroom, we had to turn off the water to the entire house.
No reason the "Pros" should do the work unsupervised. Besides, a helping hand should make the work go faster as well.
Laundry ... Gotta love it.
My son was taught to do his own laundry at 10 yrs. old, as well as to clean his own bathroom, Also, how to cook and change oil in the car. He can sew too.
Although he was my only at that time, I thought it was in his best interest to train him in all things. Its harder and takes longer to train a child than to do it yourself though.
