12 Month Old (1 Year) Wake Windows
Happy birthday! At 12 months, your baby's brain is rapidly developing — walking, talking, and understanding far more than they can express. The 12-month "nap strike" is infamous: your toddler may refuse nap 2. But DON'T drop to 1 nap yet — it's a phase.
Short answer. A wake window is the amount of time a baby can comfortably stay awake between sleep periods. Wake windows lengthen with age: newborns (0–3 mo) ~45–60 minutes; 3–6 months 1.5–2.5 hours; 6–12 months 2.5–3.5 hours; 1–2 years 4–6 hours. Putting a baby down at the right wake window — when they're sleepy but not yet overtired — is the single biggest lever for nap success. Nestling's AI tracks your baby's actual wake-window pattern and predicts the next nap time.

Frequently Asked Questions
Should I drop to 1 nap at 12 months?
NO — this is the #1 mistake parents make. The 12-month nap strike is temporary (1-4 weeks). Most babies need 2 naps until 13-18 months.
How much sleep does a 1 year old need?
12-14 hours total. About 2-3 hours during the day (2 naps) and 10-12 hours at night.
Why is my 12 month old waking at night again?
The 12-month regression combines separation anxiety, walking milestone, and cognitive leaps. Stick to your routine — it passes within 2-4 weeks.
