Ds stopped napping at 2.5.
What we've done instead of napping is take a rest time. That's either in my room with a movie on or in their beds with books. It lasts anywhere from one hour to 2.5 hours (depending largely on how I'm feeling, I'm also pregnant.)
I was also surprised that she was so young, because I was under the impression that kids napped until 3 and beyond, but trying to insist on a nap meant a super late bedtime (really late, like midnight), and cranky parents who didn't get any down time at night, not to mention enough sleep ourselves. So now that I've done this once I can understand how a kid could drop naps early.
And to answer the pp, mine went to one nap at about 10 months old.
We also did implement quiet time, which is where he can play quietly on his bed until the timer goes off, we're working on me being able to go downstairs and not have to sit in the doorway still though.
He went to one nap right around 10 months.
DD1 is almost 5 1/2 and still naps MOST of the time. Wakes at 7:15am (give or take 15), naps at 1pm for anywhere from 1 to 2 hours. Goes to bed at 8pm, but takes a while to fall asleep. If she doesn't nap she goes to sleep more quickly. But, I need the break (to work) during the middle of the day, so I keep the nap schedule.
DD2 is 3 1/2 and still naps every day. Wakes around 7am, naps at 1pm for 1.5 to 2.5 hours. Goes to bed at 8pm, falls asleep by 8:30 or earlier
having them both nap at 1pm allows me to work, clean, etc and gives them much better attitudes and behavior during the day.
Fortunately, if we're out and they have to skip nap time, they are pretty easy and we just make sure they're in bed early so they can catch up on rest.
They don't usually, however, sleep later if they miss a nap or go to bed late, so we really try to stick to a consistent 8pm bed time.
My DS refused naps soon after his 2nd b-day and has been happy throughout the day and now sleeps from 7:30-6:30/7am.
