DD is 2.11 and naps for 2-3 hours a day. She sleeps from 8 (well she's in bed at 8 but it takes her 30 mins to stop talking to her friends) till 6:45/7ish. We have also just stopped dummies too which might affect her naps, but since she starts afternoon kindy in Jan it's not necessarily a bad thing.
Selfishly I'd prefer that she kept napping, as a SAHM I love my me time.
