How the Sleep Tracker Works
Three taps and you're done — then both parents are in the picture
1. Baby Goes Down
Tap to start the sleep timer. Choose nap or night sleep. Optionally set a notification duration so you know when to expect them up.
2. Get Notified
Receive a push notification when your timer ends. Both parents can see the live sleep timer from their own phone — no need to ask.
3. Baby Wakes Up
Tap to stop the timer. The session is logged automatically — duration, type, and who logged it. Both partners see it in their timeline.

Everything You Need to Track Baby's Sleep
Built-In Sleep Timer
Start and stop with one tap. Duration is calculated automatically — no mental arithmetic at 3am.
Naps & Night Sleep
Log separately so you can see how much daytime sleep vs night-time sleep your baby is getting.
Real-Time Partner Sync
Either parent can log from their own phone. Both see the same live timeline instantly — no texting, no asking.
Push Notifications
Set a timer duration when you put baby down. Get notified when it ends — useful for nap caps and planning your day.

How Much Should a Baby Sleep? What's Normal by Age
Sleep needs change dramatically in the first year. Tracking helps you spot patterns — and reassures you that what you're experiencing is normal.
Newborn (0–3 months)
14–17 hours/day
Short bursts of 2–4 hours throughout the day and night. No pattern — entirely normal. Both parents tracking helps you see the bigger picture when you're too tired to remember.
3–6 months
12–16 hours/day
Longer stretches start to emerge, often 4–6 hours at night. Daytime naps begin to consolidate from many short naps into 2–3 more predictable ones.
6–9 months
12–15 hours/day
Most babies settle into 2 naps a day. Night sleep often improves, though teething and developmental leaps can disrupt things. Your sleep log helps you tell the difference.
9–12 months
11–14 hours/day
Transition towards 1 nap a day. Night sleep of 10–12 hours is common. The sleep tracker helps you time the nap transition without guessing.
Sleep ranges are general guidelines. Every baby is different — consult your health visitor or GP if you have concerns.
Night Shifts Are Easier When You're Both Looking at the Same Log
The outgoing parent logs the final sleep session. The incoming parent opens BumpSync and immediately knows when baby went down, how long they've been asleep, and what happened overnight — without waking anyone up to ask.
Partner A (night shift)
Logs every feed and sleep session overnight. Goes to bed at 6am knowing everything is captured.
The handover
No note on the fridge. No whispered debrief. Just open the app.
Partner B (day shift)
Wakes up and can see the full overnight log — last feed, last nappy, last sleep — before getting out of bed.
