What families get

NapCoach guides the day step by step

It does more than log sleep. It guides the day: shows the next step, updates the plan after every event, and keeps both parents in the same context

Nap suggestions

Plan your baby’s next nap

NapCoach uses age in weeks, the latest wake-up and logged sleep to suggest when to start the routine. Adjust to your baby’s cues.

Live day plan

Rebuilds the day after every event

Fell asleep, woke up, fed again, and the app instantly recalculates the next nap, a bridge nap, routine timing, and the bedtime target.

Notifications

Reminders around suggested nap times

First a gentle heads-up, then a clear "time to put baby down". Keep only the alerts you want and set quiet hours.

AI assistant

Answers from your baby's real data

Ask about short naps, bedtime, or whether a bridge nap makes sense. The reply uses your sleep and feeding history, not generic parenting advice.

History & insights

Brings day, week, and month into one picture

See today, 7-day and 30-day views, norm comparisons, and Excel export. You understand what is really changing instead of guessing from one rough night.

For two parents

Keeps both parents in the same context

When one parent logs an event, the other sees the updated status, plan, and history right away without retelling or screenshots.

Sleep Science

Wake Windows by Age

The time a baby can stay awake without becoming overtired changes with age every few weeks. Below are simplified ranges, and within each age the app calculates precise norms by week.

0–3 months
20 min–1 h 45 min
4–8 naps per day
3–5 months
1 h 15 min–2 h 45 min
3–5 naps per day
6–8 months
2 h 10 min–3 h 45 min
2–3 naps per day
9–12 months
2 h 45 min–4 h 30 min
2 naps per day
12–18 months
3 h 15 min–6 h
1–2 naps per day
18 months to 3 years
5 h 30 min–6 h 30 min
1 nap per day

Consensus Sleep Guidelines (24h)

AASM 2016, endorsed by AAP

  • 4–12 months: 12–16 h/day (including naps)
  • 1–2 years: 11–14 h/day
  • 3–5 years: 10–13 h/day

What NapCoach Tracks

Based on your baby's age in weeks

  • 17 age ranges: from 0 weeks to 3 years
  • Wake window: 20–390 minutes
  • Total sleep: 15–18 h (newborns) to 11.5–13.5 h (2+ years)
  • Nap transitions: 5→4, 4→3, 3→2, 2→1

What Research Confirms

Evidence-based pediatric sleep medicine

  • Chronic sleep deprivation in children is linked to worse attention, behavior, learning, and emotional regulation outcomes.
  • In infants, sleep patterns are associated with stress system markers (HPA-axis, cortisol).
  • That's why both wake window length and schedule consistency matter, not just total sleep hours.

Advice in your baby's context

No more "for babies at 3 months it's recommended...". The app knows how long Arina slept today, when she woke up and what she ate, and responds based on that specific data.

  • Shared sleep history No need to repeat context; the app remembers your recent conversation and the entire tracking history
  • Real data, not templates The prompt always includes: current status, last 24 hours log, weekly stats and age-appropriate norms
  • Practical advice only Specific next steps, no fluff. Medical questions are referred to your pediatrician

Methodology based on AAP/AASM clinical guidelines and pediatric sleep meta-analyses: Mindell et al., Sleep, 2006; Gradisar et al., Pediatrics, 2016.

Reviews

What do parents say about us?

Real stories from people who use NapCoach AI

★★★★★

"I finally understand when to put him to bed. We used to guess — now the bot gives us advance reminders. Lyova started falling asleep faster, without tears. After three weeks of using it, we started meeting the sleep norms for his age."

Maria K.
Mom of Lev, 3 months
★★★★★

"My wife and I use it together: we share the same history, so we don't need to tell each other how long Anya slept. The AI morning briefing and daily schedule are a whole other kind of magic. It really helps us plan the day."

Andrey S.
Dad of Anya, 7 weeks
★★★★★

"I messaged the bot at 3 AM about short naps. It replied in detail, taking into account how my son had slept all day. It wasn't a generic answer based on norms and textbooks — it addressed our specific situation. Just wow."

Ekaterina B.
Mom of Timofey, 5 months
Busting Myths

What people say vs. what's actually true

Three persistent misconceptions that prevent better sleep

Myth

"If you keep them up longer, they'll get tired and sleep better"

Fact

Overtiredness puts the nervous system into an excited state, making it harder to fall asleep and reducing sleep quality. Catching the "window" matters more than waiting.

Myth

"Letting them cry it out is harmful to their psyche"

Fact

A 5-year study (Price et al., Pediatrics, 2012) found no long-term differences in emotional development or attachment in children who underwent behavioral sleep intervention.

Myth

"Internet advice will work just fine"

Fact

Template recommendations don't account for age in weeks, accumulated sleep debt, or your child's actual sleep history, the data that NapCoach sees at every moment.

NapCoach AI is designed for children from birth to 3 years. The wake window database covers all periods: from 0–4 weeks to 2–3 years. After age 2 the app still works, but the need for strict tracking typically decreases.
Download NapCoach from the App Store or Google Play, sign in and set up your child’s profile. You can then log sleep and feeds. Full access requires a subscription after the trial; view the price and terms in the app before paying.
Yes, that's exactly how it's designed. Both parents see one shared sleep history. If mom marks "Fell Asleep", dad sees it in his app. AI questions from both parents go into one shared context.
The app calculates the wake window based on your baby's age (in weeks) and tracks time since the last waking. At 75% of the window it sends a warning. When the minimum wake window is reached, you get a "time to put down" reminder. When the maximum is exceeded, you get an overtiredness alert. Each notification can be toggled independently.
NapCoach AI is a sleep organization assistant, not a medical tool. The app doesn't diagnose and recommends consulting a pediatrician for any health questions. The AI specializes in sleep schedules, wake windows, bedtime routines, and feeding.
In settings (⚙️ Settings → 🔕 Quiet Hours) set a range, e.g. 10 PM–7 AM. During this time the app won't send wake window notifications. Morning and evening briefings continue on schedule, or you can disable those too.
Overtiredness is when a baby has been awake longer than their wake window. The nervous system shifts into an excited state, making it paradoxically harder to fall asleep and reducing sleep quality. That's why catching the "window", the moment of tiredness without exhaustion, is so important.
Sleep recommendations are built on AAP and AASM clinical guidelines, plus meta-analytic research: Mindell et al. (Sleep, 2006), a meta-analysis of 52 behavioral sleep intervention studies, and Gradisar et al. (Pediatrics, 2016), a randomized controlled trial. The AI applies these principles to your child's real data and does not make medical diagnoses.
An article gives generic advice for "a 3-month-old baby". NapCoach knows how much your baby slept today and this week, when they last ate, their current status, and how they compare to age norms. The response is built from this data, not a template.

NapCoach AI provides educational information about sleep schedules based on open AAP, AASM recommendations and peer-reviewed research. The service is not a medical device and does not replace pediatrician consultation. Every child is unique, so recommendations are general in nature.

Safe Sleep (AAP): always place your baby on their back, on a separate firm surface without pillows, blankets, bumpers, or toys. For any health concerns, consult your pediatrician.
