−3 hrs
of sleep, per parent, per night
A survey of 1,300 UK parents found 7 in 10 lose an average of three hours of sleep every night in the baby’s first year — about 133 nights’ worth before the first birthday.
Night shifts · for the first months
Split the night into shifts, not into fragments.
A newborn feeds 8–12 times a day, and both of you waking for all of it is how couples end up losing three hours of sleep a night, every night. The pattern that actually works is shifts: one parent fully on duty, one truly off — in another room, asleep. mybabynotes was built around that handoff: “can you take him?” is a button, the plan drafts itself from his rhythm, and the off-duty parent sleeps because it’s explicit.

What year one actually costs
The sleep math is brutal. Plan for it like adults on a rotation.
Hospitals, warehouses and ships have known this forever: when the work runs 24 hours, you don’t “take turns” — you run shifts, with a real handoff in between. The numbers on new-parent sleep say your house is now that kind of workplace.
1–3 hrs
is the longest stretch for half of new parents
Owlet’s survey of new parents found half get just 1–3 hours of uninterrupted sleep in the first six months; only 5% get a full eight. Fragmentation, not total hours, is the killer — which is exactly what shifts fix.
8–12
feeds every 24 hours, says the AAP
Newborns eat every 2–3 hours, on demand. That’s not a phase you push through on goodwill — it’s a schedule you staff. Knowing the rhythm is what makes a shift plan possible.
6 yrs
is how long parents’ sleep can stay disrupted
A study in the journal Sleep tracked parents for years: sleep satisfaction and duration don’t fully recover until the first child is about six. The habits you two build now are the ones you’ll keep.

The schedule that survives
Two blocks. One owner each. A real handoff between.
The exact hours flex around feeding choices and work schedules — the structure doesn’t. Here’s the version most couples land on, and where the app carries its share.
Split at a feed, not a clock
Something like 9pm–2am and 2am–7am, anchored to a feed that usually happens around the boundary. Track a few nights first — the History screen shows the rhythm — then draw the line where the baby already does.
Off duty means off
Other room if you can, earplugs, phone silent. One five-hour block beats eight interrupted hours — that’s the whole point of the Owlet number. The on-duty parent handles everything, and starting a cover in the app makes it explicit, not a vibe — the header says who’s covering, and says so by name.
Hand off with a plan, not a briefing
At the boundary, tap Hand it to someone else and name them. The app drafts the cover from the baby’s actual rhythm — next feeds, meds, amounts, an “until” time — so the 2am takeover needs zero conversation. When it ends you get a summary instead of the “so when did you…” interrogation.
Built for the 3am log
Entries save on the phone first and sync when there’s signal — no spinner between you and Save. The sheet opens pre-stamped with a guess at what’s next, so most logs are four taps, done one-handed over a bassinet.
Nursing? Run the modified split: your partner owns the first block with a pumped bottle — or owns everything around the feed — while you bank the early stretch. Talk to your pediatrician or an IBCLC about what fits your feeding plan.
Fair questions
How do couples split night feedings with a newborn?
Shifts, not turns: split the night into two blocks (say 9pm–2am and 2am–7am), one parent fully on duty per block, the other truly off — other room, earplugs, phone on silent. Newborns feed 8–12 times per 24 hours, so alternating every wake-up means neither of you ever sleeps more than a stretch; shifts mean you each get one long block.
What if we’re breastfeeding — can we still do shifts?
Many nursing couples run a modified split: the non-nursing partner takes a pumped-bottle feed for the first block while the nursing parent banks an early unbroken stretch — or handles everything except the feed itself: settling, diapers, getting the baby back down. Even owning half the wake-up shortens it for both of you.
Do we really need an app for this?
You need the handoff; the app just makes it cheap. Whoever takes over needs the last feed, the amount, the meds — and at 2am nobody wants a briefing. A shared log on both phones means the taking-over parent just looks; starting the cover drafts the plan, and ending it writes the summary. Paper on the fridge works too — until the 4am entry doesn’t make it downstairs.
Tonight, one of you sleeps five straight hours.
