Age-based wake windows, nap schedule, and bedtime range from newborn to 24 months.
We'll calculate the next nap or bedtime based on the age-appropriate wake window.
Wake windows by age
| Age | Wake window | Naps | Total sleep |
|---|---|---|---|
| 0–4 weeks | 45–60 min | 4–5 | 14–17 hr |
| 4–12 weeks | 60–90 min | 3–4 | 14–16 hr |
| 3–6 months | 1.5–2.5 hr | 3 | 12–15 hr |
| 6–9 months | 2–3 hr | 2 | 12–14 hr |
| 9–12 months | 2.5–3.5 hr | 2 | 12–14 hr |
| 12–18 months | 3–4 hr | 1–2 | 11–14 hr |
| 18–24 months | 4–5 hr | 1 | 11–14 hr |

Newborn Sleep Patterns (0–3 Months)
Newborns sleep 14–17 hours a day in short stretches of 2–4 hours. Day-night confusion is normal — their circadian rhythm isn't online yet. Feed-wake-sleep cycles dominate, and wake windows are only 45–60 minutes.
↑ Back to topInfant Sleep Schedule (4–11 Months)
By 4 months sleep starts consolidating: 12–16 hours total, with 2–3 naps and a longer night stretch. Many babies start sleeping through the night between 4–6 months — though "through the night" technically means 5–6 hours straight.
↑ Back to topToddler Sleep Schedule (12–24 Months)
Toddlers need 11–14 hours across one or two naps. The 15–18 month transition from two naps to one is a classic disruption point.

- 4 months: permanent change as sleep architecture matures
- 8–10 months: separation anxiety + crawling
- 12 months: walking + nap transition
- 18 months: independence and language burst
- 2 years: nightmares, big-kid bed transitions
Safe Sleep Guidelines (AAP Recommendations)
- Always place baby on their back for every sleep.
- Firm, flat sleep surface — no soft bedding, bumpers, or stuffed animals.
- Room-share without bed-sharing for the first 6–12 months.
- No overheating: dress baby in one extra layer compared to you.
- Offer a pacifier at sleep time (after breastfeeding is established).
Signs of Baby Sleep Readiness
- Glassy stare, slowing movements
- Yawning, eye rubbing, ear pulling
- Becoming fussy or losing interest in play
- Red eyebrows or mild redness around eyes
Catching these cues before full-on crying gets baby down faster — every time.
