What a 18 months old's day looks like
One midday nap, five-hour days. Watch for the 18-month regression — it is real and usually passes in 2–3 weeks.
Windows lengthen across the day: start the morning near 204 minutes after wake-up and let the final stretch before bed run closer to 311 minutes. If naps keep running short, the day is likely overtired — pull bedtime earlier rather than stretching windows.
