When lockdown started we stopped enforcing bedtimes and turned off all alarms. We were in the lucky position where the kids (3 and 5) are young enough not to have any zoom meetings, and I don't have any morning meetings.

Our family shifted to going to bed around 3am and I would wake up around 10am/11am and kids would wake up around 1pm.

We actually had to start enforcing bedtimes again because we noticed we were shifting to a 25 hour day. We got to the point where the kids were up till about 6am before we just went cold turkey and woke them up early so they would get tired sooner.

But our family are clearly night owls. We're now enforcing a 1am bedtime for the kids, and my wife and I are going to bed around 3am, and then we all wake up between 10am/11am.
