Getting started
How to track your baby's sleep with Hush
Add your baby
Sign in and add your baby's name, birthdate, and optional target bedtime. Age-based recommendations kick in immediately.
Start the first session
When your baby goes down, tap Start. Choose nap or night. Hush begins the timer and remembers the wake time when you stop it.
Log consistently for 7 days
Predictive wake windows improve as Hush learns from 7+ days of sessions. Even rough logging helps. You can edit after the fact.
Share with a caregiver
From settings, invite your partner or another caregiver by email. They see the same log and can add sessions from their own device.
Review weekly patterns
Open the history view to see trends over the last week, month, or three months. Tap any day for a detailed breakdown.

Why track your baby's sleep?
Understanding your baby's sleep patterns helps you establish healthy routines and identify potential issues early. Tracking sleep duration and timing can reveal natural rhythms that make scheduling naps and bedtime easier for the whole family.
How much sleep does my baby need?
- Newborn (0-3 months): 14-17 hours per 24 hours, including naps.
- Infant (4-11 months): 12-16 hours per 24 hours, including naps.
- Toddler (1-2 years): 11-14 hours per 24 hours, including naps.

Understanding wake windows
Wake windows are the time awake between sleep sessions. Hush uses age settings and recent sleep logs to suggest possible timing. These estimates are not schedules prescribed by the WHO or AAP. Watch your baby's cues and adjust the plan as needed.
Tips for better baby sleep
Establish a consistent bedtime routine, keep the room dark and cool, and watch for sleepy cues like yawning or eye rubbing. Use this tracker to identify your baby's natural sleep windows and build a schedule around them.
From a newborn's erratic catnaps to a toddler's single afternoon nap, the tracker adapts to any age. Read our guide on reading your baby's sleep cues.
FAQ
Frequently asked questions
How much sleep does my baby need?
Newborns (0-3 months) need 14-17 hours, infants (4-11 months) need 12-16 hours, and toddlers (1-2 years) need 11-14 hours per day. This includes both naps and nighttime sleep.
What are wake windows?
Wake windows are periods of time awake between sleep sessions. Hush estimates possible sleep timing from age settings and logged patterns. These estimates are not deadlines or WHO/AAP-prescribed schedules. Your baby's cues come first.
How is the sleep score calculated?
The optional history score summarizes the logged day against Hush's age settings. It is not a clinically validated health score. No score is displayed for babies under 4 months.
Is my data private?
Yes. Your sleep log is stored in your private Babysential account, protected by row-level security so only you and caregivers you invite can see it. We never share or sell your data.
Can I share sleep logs with my partner?
Yes. From Hush settings you can invite a partner, grandparent, or caregiver by email. They see the same sleep log and can add sessions from their own device.
Where does the science come from?
Age-based sleep recommendations follow AAP (American Academy of Pediatrics) and WHO guidance. See our guide on how the sleep score works for the full methodology.
