Baby sleep tracker for naps, nights and clearer handovers

Sleep is easier to talk about when both caregivers can see the last nap and how long baby has been awake. Luna’s baby sleep tracker lets you log falling asleep and waking, then shows naps, overnight stretches and wake-window style context from your recent patterns: in plain language, not percentile charts.

Luna does not teach sleep training, diagnose sleep problems or tell you how long your baby “should” sleep. For NHS information about babies and safe sleep topics, start at the NHS baby hub and NHS guidance on sudden infant death syndrome (SIDS). Always follow current advice from your midwife or qualified health professional for how your baby sleeps.

What sleep tracking includes in Luna

• Log sleep start / wake in the app or via connector tool log_sleep.
• See asleep/awake state and duration in live status (get_status / live API).
• Nap and overnight totals in day and week views (get_today, get_week_review).
• Next nap window and bedtime-style estimates derived from logged patterns: organisational prompts for handovers, not medical targets.
• Wake-window style wording compared with what is typical for your logged data, without percentile jargon (as stated on /connector).
• Shared visibility for partners, grandparents and other invited caregivers.

How to use it tonight

1. Create your free family log at /onboard.
2. When baby falls asleep, log sleep; when they wake, log the wake.
3. Before a handover, open the timeline or ask a connected assistant for status (“are they asleep?”).
4. Fix mistakes with edit/undo rather than leaving a wrong nap on the day.
5. Keep feeds and nappies on the same timeline so night shifts see the whole picture.

Related sleep searches this pillar covers

People also search for newborn sleep tracker, sleep tracker app, sleep schedule tracker, nap tracker, sleep log, sleep diary and wake window tracker. In Luna those are the same sleep events with different questions on top:

• Newborn days → frequent short naps, still one log.
• Schedule curiosity → review your logged timings; Luna does not impose a schedule.
• Diary / log → the timeline is the diary, shared automatically.
• Wake windows → shown as context from recent awake stretches, not a rigid rulebook.

Making sleep logs useful for the next adult on shift

A sleep tracker earns its keep at handover. Before you leave for work, your partner should be able to open Luna and answer: is baby asleep now, when did the last nap end, and how long have they been awake? Live status is designed for that glance. Week review sleep totals help you talk about “how nights have been” using numbers you actually entered, not vibes.

If you prefer voice, a connected assistant can call log_sleep and get_status with your token. Proactive nudges may mention nap windows opening: optional organisational prompts, not orders.

Patterns without pressure

Parents often want to know whether naps are “getting longer.” Luna can show what you logged across days. That is different from declaring a developmental milestone or a sleep-training success metric. Keep the emotional stakes low: the log is a shared notebook with timestamps.

Helpful habits:

• Log sleep start when you put baby down if that matches how your family defines sleep; be consistent between caregivers.
• Log wakes when the day truly resumes, so awake duration means the same thing to both of you.
• Avoid double-logging when both parents notice a wake: edit instead.
• Pair sleep with feeds and nappies on the same day view so night shifts see interactions without scrolling three apps.

What we will not put on this page

You will not find “sleep through the night by week X,” cry-it-out instructions, or claimed safe-sleep product endorsements here. For NHS information on SIDS and baby care, use the NHS links in the safety section. Your midwife or qualified health professional remains the right place for personal sleep questions.

Want calm answers from your own log?

Free Luna already keeps the shared tracker and the assistant connector. Luna Plus (£3.99/mo) adds Ask Luna: answers and summaries grounded in what your family has actually logged, in the app or through a connected assistant such as Meta Muse or Claude.

With Plus, ask “how did naps look today?” and get a summary from the sleeps you logged: useful before bedtime handover.
