I think I’ve seen this somewhere before, and I agree. When my daughter had severe health issues, we were able to handle it largely because I’m a night person and my wife is a morning person. I would stay up until 4 or so and she would wake up at 5, so there was a maximum of 1 hour that no one was awake to check on our daughter. It would have been easier if I wasn’t working a standard day-shift job (on 4-5 hours sleep).
I’m now lucky to be in a job where we have a mix of both morning and night people and people working remotely from various timezones. They just treat me like one of the people who’s in another timezone. It mostly works out well. Those jobs are rare though.
