A "wake window" is how long a baby can stay awake without tipping past the point of overtiredness. Respecting it is the difference between a peaceful nap and a 40-minute battle with a baby too exhausted to sleep.
Typical windows by age
Every baby is different, but these ranges are a good starting point:
- 0–1 month: 40 to 60 minutes awake.
- 1–3 months: 60 to 90 minutes.
- 3–6 months: 1.5 to 2.5 hours.
- 6–9 months: 2 to 3 hours.
- 9–12 months: 2.5 to 3.5 hours.
The sign that the window is closing usually comes before the crying: a distant stare, a yawn, eye rubbing, losing interest in the toy.
How tracking helps
Knowing when the last nap ended is the missing piece of data at 3 p.m., when nobody remembers anything anymore. That's exactly why neneco estimates the next nap: it blends the typical window for your baby's age with what you've logged over the last few days — and shows on the home screen when the next window should open.
No estimate replaces what you see in your own baby (or your pediatrician). But hitting the right window, crib ready, is a game changer.
