A key sign a child may be ready to drop a second nap is consistent, solid overnight sleep, typically around 10–12 hours.
Children who are active, alert, and not irritable throughout the morning may be getting enough rest to stay awake until midday.
Being able to make it to lunchtime comfortably and then take a single midday nap is an indicator of readiness.
A late afternoon nap can interfere with falling asleep at the normal bedtime.
If a child struggles to fall asleep at night after a late second nap, it may signal they are ready to transition to one nap per day.
