We've been doing some painting in our house in the evenings when the kids go to bed. This restricts our painting hours considerably, but at least we don't have to worry about any unapproved finger painting. To try to take advantage of our time, we try to do some simple things while the kids are awake, like taping cabinetry. Even that simple task leads to interference from the offspring.
As soon as Brian set up the step stool they were on it wanting to tape the walls like daddy. I told them to hold on to that dream for a few more years and we would have no problem putting them to work.
