Usually 1-2 naps with most kids transitioning from 2 naps down to 1 afternoon nap around 14-18 months. It really depends on the child and how much nighttime sleep they are getting. Most 1 year olds need about 12-14 hours of sleep per day. Adding up nighttime sleep with hours from both naps can help guide your decision. See above for my how-to guide when dropping the morning nap.
