If you recognise two or more of these, the six-question assessment will tell you which approach the research points to for your baby.
You aren't sure why, what changed, or whether tonight will be yet another two-hour battle.
And they absolutely cannot get back to sleep without your help—no matter how long it takes.
You try a different trick every night, and now you’ve completely lost track of what actually helped.
You have read six different experts who all contradict each other, leaving you more confused than when you started.
Your baby might be catching up on sleep during the day, but you are the one surviving on broken sleep and coffee.
You don't want another opinion, a generic blog post, or a philosophy. You just want step-by-step instructions for what to do tonight.
A recent study followed 326 children from seven months to six years old. Over that time, their total night-time sleep barely changed. What did change was how often they woke their parents.
Take the free, 6-question assessment. In 3 minutes, it will tell you exactly which of the 5 research-backed approaches is the right fit for your baby—with no email required.
Find My Best Starting Approach →“I have three kids. By the third, I had read enough contradictory sleep advice to last a lifetime. Every book was certain they had the definitive answer, yet none of them could explain why a trick that worked perfectly for my oldest did absolutely nothing for my youngest.”
“So I stopped reading books and went straight to the raw data. I wanted to see the randomized trials and the studies that actually tracked these kids for years.”
“It turns out the actual science is surprisingly straightforward. It also contradicts almost every bestseller out there. There is no single magic method. But there are a handful that actually work, and the data just gives you a map to figure out which one fits your kid.”
Three stages. The first one is free and takes three minutes.
What the problem looks like, how they handle you leaving, and what you are genuinely comfortable doing. Free, no email needed.
Bedtime routine and daily rhythm before any settling method. Four trials, 829 children, and some families never need to go further.
One screen per night. What to do at bedtime, what to do at each waking, what is normal tonight, and what to do when it goes wrong.
Everything below is included. There is nothing else to buy.
One of five approaches with research behind it, chosen around your child and around you. All five are included, not just yours.
One screen per night, with audio for every night, because at 2am you cannot read.
Teething, illness, travel, regressions, early waking, split nights, short naps, cot to bed, night terrors. Searchable at 3am.
Is-this-normal checker, wake windows, nap timing, check-in intervals, bedtime shifting, feed reduction. Worked out for your child's age.
Two full modules, plus the toddler and preschooler track running to five years.
A one-page summary you can hand to your partner, one for grandparents, one for daycare, so you are not explaining it six times.
A trial compared two of the most common approaches directly, in babies aged nine to eighteen months. Both improved sleep overall. But split by how the babies handled separation, something turned up that should be on the front of every sleep programme sold.
Babies who became very distressed when a parent left showed no significant change in how long they were awake at night on the interval-checking method. The same babies improved clearly when a parent stayed in the room instead. The authors concluded that parent-present approaches should be favoured for infants like those.
You are going to be asked this, possibly by your own mother. Here is what has actually been measured, with the caveats left in.
Infant cortisol tracked over twelve months. It declined and stayed within normal limits. Nobody measured cortisol during the actual nights of crying, so short spikes cannot be ruled out—what the follow-up did not find was any lasting elevation.
Attachment assessed at twelve months using the standard laboratory measure, scored blind. No significant difference. Behaviour and mental health measured at twelve months and again at six years old, with no difference either time.
At six years the researchers also collected salivary cortisol as an objective stress measure, five years after the intervention. 28.8% versus 21.7%, p=0.4. The authors conclude the benefits fade too—no marked long-lasting effects in either direction.
