Yes, using power tools while kid is napping is no-go. But after few months kid is not napping that much. And there’re many relatively silent jobs. It’s easy to silicon a window sill while kid is sleeping in another room. Or assemble a drawer with an old good screwdriver instead of a drill. And after a couple years there’re endless learning possibilities. Sure, it goes slowly, but it does happen eventually.

Full disclosure - I did hire handymen for a good portion of jobs for various reasons. Mostly because we were burning a lot of money in rent or some jobs require too many special tools and knowledge to be done right (electricity, drywalls, etc).
