What a 9 months old's day looks like
Two solid naps is the norm. Separation anxiety can fight bedtime — a consistent wind-down beats a longer window.
Windows lengthen across the day: start the morning near 128 minutes after wake-up and let the final stretch before bed run closer to 199 minutes. If naps keep running short, the day is likely overtired — pull bedtime earlier rather than stretching windows.
