What a 4 months old's day looks like
The famous 4-month regression hits here: sleep cycles mature and short naps appear. See our 4-month sleep regression guide.
Windows lengthen across the day: start the morning near 77 minutes after wake-up and let the final stretch before bed run closer to 121 minutes. If naps keep running short, the day is likely overtired — pull bedtime earlier rather than stretching windows.
