12 to 21 months: Phasing Out the Morning Nap
Most babies don't make this leap until 15 to 21 months, although some do it as early as a year. The transition to a one-nap day can be rough, and it probably won't happen overnight. You might go through a few months when two naps seem like too many while one isn't enough. Some people have luck with alternating the schedule: One day baby has one nap (and an earlier bedtime), the next day she has two. Most kids need a nap every day until age 3, even though they might not cooperate or seem to want one.
No naps make for a long day (especially for Mommy), so hold on to that afternoon nap as long as you possibly can. When Chloe was born, I was looking forward to simultaneous naps for the girls, which would afford me a little downtime, but almost-3-year-old Samantha was not having it. Alas, when siesta time is over, it's so over. There's nothing to do but bid a sad farewell. It was good while it lasted!
