It cannot be understated how much kids interrupt the ability to focus on tasks. The ability to do nothing but focus on solving on a problem for a week straight felt like 100x the productivity of having to totally context switch at the end of the day to someone needing a juice or going into a screaming tantrum because the color of the cup is wrong and that being non-stop until the next work-day, which totally obliterates all the short-term working memory you had of the task at hand.
