Baby sleep
How to choose a baby sleep tracker without an account
A sleep tracker is most useful when it helps you remember when the last sleep began and ended. It does not need a profile, a feed, or a permanent connection to do that.
Keep the sleep log simple
Start and end times are enough for many families. Notes are useful for context, but a simple timeline is more likely to survive a difficult night than a long form.
Over several days, the record can help you see how sleep periods are changing without needing to remember every detail.
Choose the privacy model deliberately
Before using an app, check whether sleep data is kept on the phone or uploaded to a service, and whether an account is required before you can log the first nap.
Buggy works without a login and keeps the baby record on the device. That makes it usable offline as well as private by default.
Do not treat a sleep log as medical advice
A log is a memory aid, not a diagnosis. It can make a professional conversation easier, but sleep safety and health concerns should always be discussed with a qualified clinician.
