Non routine/schedule parents — how do you do it?

I am not a super strict parent by any means, however, we have a general routine down. I have a 3 and 1 year old who have a bedtime of 8/8:30. So much so that if we’re out my 1 year old will start losing it past 8:30 if he’s not put down.

Kids wake up around 7:30an. They both nap around 1pm. Have lunch after they wake up, etc. Again, not super rigid, but I have a general schedule.

I’m genuinely curious for parents who don’t have a routine: how do you do it?? How do you navigate your day? How do you even get by your day? Not judging at all, I’m just so curious.

As I put kids right now, I’m so thankful to have some time to myself. Since there’s no schedule for you, is alone time unexpected?
