Children’s clocks don’t. So bedtime feels an hour earlier and so does getting up to get ready for the day. It’s not the end of the world but it’s just one more thing to be like “ok let’s plan on two weeks out of the year to just be fucked because we got this outdated thing that doesn’t matter anymore but actually does just fuck with sleep schedules.”
I say this as someone who very much thought this factor was overstated and people complaining were mostly whiners…before I had kids. I still say it’s not the end of the world but it feels like a lot of hassle for not much reward. Just get rid of it
