Author’s practical guidance
Does letting them cry do harm?
Source named in the book: randomized trials and long-term follow-up (Hiscock)
This is the question under every argument about sleep, and it has been studied.
Say this now
(to yourself) "This is a choice about our household, not a risk to him."
Guilt, not crying, is what usually ends the plan.
(to each other) "Which of these can we both actually do?"
The right method is the one you can both run for a fortnight.
Do this
- Pick the approach you can hold — gradual withdrawal, timed checks or bedtime fading.
- Read what the method says, not what its opponents say it says.
- Stop if it is doing harm to you — that is a legitimate reason, not a failure.
- Give it two weeks before judging whether it suits your child.
- Keep the daytime unchanged — more time together, not less.
Avoid this
- Using it to push a partner into a method they cannot run — a plan one adult hates fails by night three.
- Reading it as an instruction to sleep train — no evidence says you must do anything.
- Continuing something that feels wrong because a study exists — you have to be able to run it two weeks.
If it repeats
If you have tried and stopped several times, stop looking for a better method. What ends these attempts is the middle of the second week, and the fix is a plan for those nights: who is on, what gets said, what happens if it goes badly.
Why the book suggests this
This is the question under every argument about sleep, and it has been studied. Families were randomly assigned to a planned approach or to usual care and followed for years. Hiscock's group found no differences in emotional or behavioral problems, in the parent-child relationship or in stress measures.
That is a real answer with real limits. It covers structured approaches run by supported parents, not any night in any house. What it rules out is the claim that a planned approach leaves damage behind.
