How do I know the right bedtime for my baby?
The best bedtime depends on your baby’s age and when they woke from their last nap. The estimator gives you a bedtime window that fits the usual wake window, which helps reduce overtiredness.
What if my baby still fights bedtime?
Resistance often means the wake window was too short or too long. Try adjusting bedtime by 15–20 minutes earlier or later.
Can I use this estimator for toddlers?
Yes. The age field covers **0 to 36 months**, and wake windows get longer as your child grows. Under 3 months, bedtime is naturally less predictable, so use the result loosely.
What if naps are irregular or skipped?
On skipped nap days, move bedtime earlier. On days with late naps, cap nap length to avoid pushing bedtime too late.
Will this fix night wakings?
Not always. A bedtime that fits the wake window can reduce overtiredness, but night wakings can also be linked to hunger, regressions, or developmental milestones.
Should I always follow the suggested window?
No tool replaces parental observation. Use the bedtime window as a **guide**, but let your baby’s cues lead.
What is overtiredness in babies?
It's when a baby has been awake longer than they can comfortably manage. Overtired children may get sudden bursts of energy, get upset easily and resist sleep even though they're very tired, which makes settling harder.
What happens if my baby gets overtired?
They may fight sleep and be harder to settle, and naps or the night can be more broken. Keep wind-down short and calm. One overtired day is common and doesn't need a big schedule change.
What if my baby seems happy past the upper limit?
Some babies seem wired when they're actually overtired. Others really are fine for a bit longer. If they're calm and engaged, a short stretch is usually OK. If they're suddenly hyper or upset, start winding down.
Can I use this for naps and bedtime?
Yes. Enter the time your baby woke from their last sleep, whether that was a nap or the night: the bedtime window and the live check both work from it.
