    What a 3 months old's day looks like

    Naps may start consolidating. If the last window ends in a meltdown, pull bedtime earlier rather than adding a nap.

    Windows lengthen across the day: start the morning near 64 minutes after wake-up and let the final stretch before bed run closer to 103 minutes. If naps keep running short, the day is likely overtired — pull bedtime earlier rather than stretching windows.
