Bedtime is different there
Source named in the book: research on bedtime regularity (Mindell)
You will not get the two bedtimes to match, and the attempt usually costs more than the mismatch does.
Say this now
“Different houses, different bedtimes. Here it's this one.”
States both without ranking them.
“You're tired from the weekend. Bed is the same time.”
Acknowledges it and changes nothing.
Do this
- Aim for your normal window and let the return night land within half an hour of it.
- Make Monday evening lighter instead of earlier — fewer demands, same clock.
- Expect a rough Monday for the first few months and stop reading it as a verdict.
- Say the bedtime out loud on arrival so it is not a surprise at seven.
- Ask nothing about the other bedtime. Not once.
Avoid this
- "You're going to bed early because of Dad." Makes your bedtime a punishment for his.
- An hour earlier on Monday to catch up. It rarely works and it moves the anchor.
- "What time did you actually go to bed?" Turns them into the source of evidence.
If it repeats
If Mondays stay hard for longer than a few months, look at your own evening rather than at his. Return days usually carry a backlog of chores and questions that no child could absorb on top of a change of house.
Why the book suggests this
You will not get the two bedtimes to match, and the attempt usually costs more than the mismatch does. Research on bedtime regularity keeps finding that consistency of timing matters more than the hour chosen, which puts the useful work on your side of the week rather than his.
The instinct is to compensate — earlier, stricter, a lecture about how it is at Dad's. Trials of bedtime routines point the other way: what makes a routine work is that the time holds steady. Bending it to absorb the weekend breaks the one thing you control.
