My DD is the same, never really needed a lot of sleep although she is a good sleeper - I just mean if she doesn't have a sleep if we're out somewhere where she can't sleep or our day is interrupted etc, she is fine, no cranky pants at all.

She turned 2 in January and still has a sleep from about 12.30pm/1pm usually till about 3pm. She goes to bed at night between 7pm and 7.30pm but I agree with Lucy, I think they need a bit of wind down time just like us, and on occasion I've heard her in her room still awake about 40 mins after we've put her down. Just talking quietly to herself, no crying or anything, and that's totally fine with me.
