  "description": "A 'wake window' is the amount of time a baby can comfortably stay awake between sleep periods before overtiredness makes falling asleep harder, and it changes fast in the first two years — a newborn maxes out around 45-60 minutes awake, while a 2-year-old can go 5-6 hours. This calculator takes your baby's age and last wake-up time, applies an age-appropriate wake window range, and projects the next nap time and likely bedtime, giving you a same-day schedule instead of a generic age-based chart you have to do math on yourself.",
  "formula": "Next sleep time = last wake time + age-based wake window; bedtime = last nap end + final wake window, targeting age-appropriate total daily sleep.",

  "faq": [
    {
      "q": "What happens if I miss the wake window and let my baby stay up longer?",
      "a": "Past the ideal window, babies release cortisol and adrenaline to power through tiredness, which often makes falling asleep harder and naps shorter, not easier — the common 'overtired and wired' pattern. Watching for early sleepy cues (rubbing eyes, staring off, slowing down) and acting a few minutes before the window closes usually beats waiting for obvious meltdown signs."
    },
    {
      "q": "Why do wake windows vary so much even at the same age?",
      "a": "These are ranges, not fixed rules — temperament, how well the last sleep period went, growth spurts, and illness all shift things day to day. Use this as a starting estimate and adjust by 15-30 minutes based on how your specific baby responds over a few days."
    },
    {
      "q": "When should naps transition from multiple to fewer per day?",
      "a": "Common transition points are 4-to-3 naps around 6 months, 3-to-2 around 6-9 months, 2-to-1 around 15-18 months, and dropping the last nap between 3-5 years. Signs of readiness include consistently fighting a nap or it pushing bedtime too late, not just hitting an age milestone."
