Why we don’t use cry-it-out
Full extinction - leaving a baby until morning without returning - is effective and quick. We do not build plans around it, and it is worth being clear about why, without pretending the people who use it have done something wrong.

First, the honest part: the research on extinction methods does not show harm. Studies following children years afterwards have found no differences in attachment security, behaviour or emotional development. Anyone telling you it causes lasting damage is going beyond what the evidence supports, and parents who have used it do not need to feel guilty.
So the objection is not that it is dangerous. It is that it is a poor fit for how we think this work should be done, and for what most of the families we speak to are actually asking for.
Why we build differently
Most parents cannot complete it. And a half-finished extinction is worse than never starting: the baby learns that sustained crying eventually brings someone, which is a harder lesson to unlearn than the original habit.
It assumes the timing is already right. A great many sleep problems are wake windows and bedtimes rather than settling. Extinction applied to a scheduling problem produces a lot of crying and no result.
It does not fit the ages people ask about. Under four months it is inappropriate. During separation anxiety it works against the developmental grain. That removes much of the first eighteen months.
It cannot bend. Teeth, illness, travel and leaps all require flexibility, and a method with no dial to turn down gets abandoned rather than adjusted.
The gentler methods get there too. Slower - weeks rather than nights - but with an approach parents can actually sustain, which is what determines whether it works at all.
What we do instead
Fix the timing first, because it is often the whole answer. Then, if settling still needs work, move the point of falling asleep gradually, with a parent present, reducing help in steps over several weeks. It is slower and it is duller and it is much easier to keep doing.
Nothing in our plans requires you to leave your baby to cry, and nothing requires you to be in the room either. Both are compatible with the approach.
The best method is the one you will still be doing on night four. That rules out more than the ethics do.
If you have already used it
Nothing is broken. The evidence is reassuring, your baby is fine, and if it worked then there is no reason to revisit it. This is a statement of how we work, not a verdict on how you did.
And if you tried it and could not finish, that is not a failure of nerve. It is information about which method suits you, and it points at the gradual approaches rather than away from all of them.
What we mean by gentle
It is worth being precise, because the word gets used loosely. We do not mean no crying - a baby who has always been rocked to sleep will object when that changes, whatever approach you use, and pretending otherwise sets people up to abandon at the first protest.
What we mean is that a parent stays and responds, that protest is answered rather than waited out, and that distress is a stop signal rather than a stage. That is a real distinction and it produces a real difference in what the fortnight feels like - for the baby, and considerably more for the adults listening.
What the evidence actually says
Worth stating plainly, in both directions. Controlled trials of extinction and graduated extinction have found them effective at reducing night waking, and follow-up studies years later have found no differences in attachment, behaviour or emotional development. There is no good evidence of lasting harm.
There is also no good evidence that they are better than gentler approaches given enough time - the difference is speed, not destination. So the choice is not between a method that works and one that does not. It is between a fast approach many parents cannot complete and a slow one most can, and completion is what determines the outcome.
When to stop troubleshooting
Never start any settling programme with a baby who is unwell, in pain or not gaining weight. Inconsolable crying, crying that sounds like pain, or a baby who cannot be comforted at all, means stopping and speaking to your GP or health visitor.
