Plain-language answers about baby sleep, drawn from published research — and honest about what nobody knows yet.
Most infant sleep “problems” are inside the normal range. Some are not, and some are the parent running on empty. Here is how to tell which you have, what to try for free first, and the seven signs structured help is worth paying for.
No licence, no universal certification, and no pediatric guideline that mentions them. So what should a good infant sleep consultant actually do for you? An intake, a screen, a plan, a support window — and here is what each should look like.
Every baby wakes at night — even the ones whose parents say they sleep through. What changes with age is whether they call for you. Here is what the overnight video studies actually show.
Bedtime fading, fading the feed-to-sleep link, camping out, graduated checks — what each one actually is, what the trials found, which ages they apply to, and why the method you can do consistently beats the “best” one.
If you only change one thing about your baby’s sleep, change this. A short, consistent bedtime routine is the best-supported single intervention in infant sleep — and most of the benefit shows up within three nights.
Not a chart of averages — the real ranges at each age, what is changing in your baby’s sleep, what to expect from naps and nights, and how to use wake windows without being ruled by them.
The American Academy of Pediatrics safe-sleep recommendations, in plain language — plus the three under-communicated numbers that matter most: unaccustomed tummy sleep, sofas, and head covering.
No peer-reviewed study defines, tests or measures a “sleep regression” at four months — or at any age. What is real is a remarkable reorganisation of sleep between two and five months. Here is what it looks like from the inside.
The number you have seen — around thirteen hours a day — is an average. The normal range at six months runs from under nine hours to seventeen. Why that matters, and what to look at instead of the chart.
The widely shared study on infant sound machines measured how loud they *can* go, not whether they harm hearing. Here is what it found, and the four-rule way to use one sensibly.
