Keep the kids at home. The only time to work is at night after everyone is asleep and it is quiet. Time trying to work during the day will be wasted due to constant interruptions and thinking about other things, and you'll be frustrated as well.
This means during the 16 day hours you need to take them 8 hrs and your partner needs to take them the other 8 hours. That means you aren't spending much time together. That's right, that's how this will work.
In the old days professionals made enough cash to hire a professional staff to raise the kids at home, and later off to boarding school. This is not possible now since most IT jobs that pay well are in areas that have such a high cost of living there is no money to hire a staff. Staff is for executive level folks that make $3 million +.
