If you’re a new parent running on empty—even if your sleep tracker insists you’ve had a decent night’s kip—you’re not imagining it. A new study presented at the SLEEP 2025 annual meeting reveals that while new mums may eventually return to their pre-baby sleep totals, *how* they sleep remains profoundly different… and frequently disrupted.
Researchers from Washington State University’s Sleep and Performance Research Centre tracked the sleep patterns of 41 first-time mums (aged 26 to 43), collecting data from their Fitbits beginning a year before birth and continuing through their baby’s first birthday.
During the first week post-birth, these mums averaged just 4.4 hours of sleep per night—a sharp dip from their pre-baby average of 7.8 hours. Even more striking, their longest stretch of uninterrupted sleep shrank from 5.6 hours to a mere 2.2. By the time their babies were 2 to 3 months old, mums were still only getting around 4.1 hours of continuous shut-eye—well under what they were used to before becoming parents.
Dr Teresa Lillis, the lead author of the study and an adjunct professor at Rush University Medical Centre, explains: “Mums do tend to regain their total nightly sleep after those early weeks, but the structure of their sleep stays changed.” In other words, it’s not just about how *much* you sleep—but whether you manage to stay asleep. And that has a big impact on how rested (or not) you feel.
Broken sleep isn’t just annoying—it can affect both your mental and physical wellbeing. Dr Lillis notes that this type of fragmented sleep may contribute to postnatal depression and other health challenges.
So while advice like “nap when the baby naps” isn’t exactly wrong, this research suggests we need to go further: New mums need support to get longer, more restful blocks of sleep—not just a few extra minutes here and there.
The bottom line? If you’re a mum feeling utterly shattered despite technically getting “enough” sleep, there’s a reason. Your rest is likely still fragmented and far less restorative than it once was—and that really does matter. We need to shift the conversation from just *how much* sleep new mums get, to *how well* they sleep.
At Happiest Baby, we understand that exhaustion isn’t just a passing inconvenience—it can affect every part of your life. That’s why we created SNOO. Our award-winning smart bassinet automatically responds to your baby’s cries with gentle rocking and white noise, helping them drift off and stay asleep…so you can enjoy more uninterrupted rest, too. In fact, SNOO adds 1–2+ hours of sleep per night, helping tired parents get the deep, consistent sleep they need to feel like themselves again.

Le lait maternel est la meilleure source de nutrition pour les bébés. Il est important que, en préparation et pendant l'allaitement, les mères adoptent une alimentation saine et équilibrée. La combinaison de l'allaitement au sein et au biberon dans les premières semaines de vie peut réduire la production de lait maternel de la mère et il est difficile de revenir sur la décision de ne pas allaiter. Si vous décidez d'utiliser une préparation pour nourrissons, vous devez suivre les instructions avec soin.
