I also have a child who won't sleep, too mobile to leave on her own etc. I'm afraid that in order to get any cooked food down her neck, I - please don't judge me- cook with her in a hip sling. I give her a rice cake/whatever as a distraction, do minimal chopping, put all pans on the back burner with handles facing away so she can't reach... yes I know, it's a salutory tale waiting to happen, but otherwise I would have to strap her in her high chair and leave her to scream. And so far we haven't had a hint of a mishap because I am VERY careful. All my clothes have semi-masticated rice cake mashed down the front, though. Re the nappies, have found humane restraints work a treat. Just strap the little buggers down. Some great products here .
