Questions, answered plainly
How does the wake-window calculator produce a range?
It selects a rough Buggy planning band from the baby's age and adds the lower and upper times to the most recent wake time. These bands are not an official AAP or CDC schedule.
Should I follow the calculated time exactly?
No. Treat it as a loose planning estimate, follow your baby's cues, keep safe-sleep guidance separate, and ask a qualified professional about health or persistent sleep concerns.
