I know some doctors who have work schedules very similar to what you describe. Working around 10 days a month, but for really long shifts, around 16-18 hours (for example 15 to 8 is typical in rural health clinics, so that there is someone to cover emergencies while the doctors with the "standard" 8 to 15 schedule are not working). Not everyone likes that schedule, but some really prefer it and actively choose it over more "standard" schedules. Especially those who have small children. They have around 20 days a month to be with their children as long as needed, and only have to worry about whom to leave them with during the other 10 days. Couples where both are doctors, and both have this time table, have the kids problem fully solved by just picking different days to work.
