Quick answer: How to track baby sleep: log the time your baby falls asleep and wakes for every nap and night stretch, then look at daily totals, nap count and the longest stretch over a week. That shows patterns like late naps or long wake windows. Keep it simple, and remember a log records sleep; it doesn't monitor your baby.
TL;DR
- Log start and end of each sleep.
- Look at totals and patterns over a week.
- A log isn't a monitor: follow safe sleep rules.
Learning how to track baby sleep can turn foggy days into clear patterns. Here's what to record, and what to do with it.
What to log
| Item | Why |
|---|---|
| Sleep start | Wake windows and bedtime |
| Sleep end | Nap length and total sleep |
| Where (crib, car, arms) | Spot sleep that should move to a flat surface |
| Night wakings and feeds | Night pattern |
| Notes (illness, vaccines) | Explain off days |
Reading the data
Compare your baby's daily total with the ranges in how much sleep a baby needs. Look for the gap between waking and the next nap: if your baby fights naps, the wake window may be too long or too short. The nap schedule calculator suggests a plan.
Paper or app
A printable baby tracker works. An app does the maths: Tot logs naps and night sleep with start and end times and shows totals and trends by day and week, shared with whoever's caring for your baby.
When a sleep log helps your doctor
Bring a week of sleep data if you're worried about very short sleep, frequent night waking or snoring. Patterns are more useful than single bad nights.
Don't over-track
If logging makes you anxious, log only night sleep, or stop for a while. It's a tool, not a test.

FAQ
Should I track every nap?
For a week or two it helps you see patterns; after that, optional.
What's a good longest stretch?
It varies widely with age; many babies still wake at night in the first year.
Can an app tell if my baby is asleep?
Tot doesn't detect sleep; you log it. It's not a baby monitor.
Should I track sleep in the car?
Yes if it counts toward naps; move your baby to a flat surface when you can.
How long should I track sleep?
As long as it helps. Many families track for the first few months.
