When do babies drop to one nap?

Most babies move from two naps to one between 8 and 15 months, with the change often landing around the first birthday. The American Academy of Pediatrics and CDC describe 11–14 hours of sleep for toddlers aged 1–2 years, which fits a single midday nap plus night sleep.

How long does a nap transition take?

Plan on one to two weeks. Shift nap time later by 15–30 minutes every two or three days, keep bedtime anchored, and expect a few short or skipped naps while the new rhythm settles.

What happens if I drop a nap too early?

An overtired child often fights sleep harder, wakes more at night, and melts down by dinner. If that happens, restore the old schedule for a few days or offer a short early-afternoon nap, then try again in one to two weeks.
