The first nights in the second bed
Source named in the book: research on overnight care in early childhood (McIntosh)
Researchers disagree about a great deal in this area, but not about this: the first run of nights is a settling-in period with its own timeline, not a test the arrangement passes or fails.
Say this now
“New beds feel strange for a while. Then they don't.”
Names it as temporary, which is the true part.
“Your bed here is waiting. It stays yours.”
They are checking whether this house held.
Do this
- Send the same bedding or pillowcase so one thing smells right.
- Keep the order of the routine identical in both houses, even if the timing differs.
- Agree one short call, at a fixed time, before the routine starts.
- Give it three full cycles before changing anything.
- Say goodnight the same way in both houses.
Avoid this
- Calling it off after two bad nights. The adjustment has not started yet.
- "Was it scary sleeping there?" Supplies the frame they will use next week.
- Long phone calls at bedtime from the other house. They wake the child up.
If it repeats
If it has not settled after six or eight weeks, look at what differs between the two bedtimes rather than at the child. Order, light and who leaves the room matter more than the house does.
Why the book suggests this
Researchers disagree about a great deal in this area, but not about this: the first run of nights is a settling-in period with its own timeline, not a test the arrangement passes or fails. Small children sleep badly in a new room and then they stop, and the second week looks nothing like the first.
The temptation is to draw conclusions from nights one to three. Those are the least informative nights there will ever be, and acting on them tends to restart the clock rather than move it forward.
