My DD is 2.5 also and she generally follows this pattern:

Wakes up at 7.30am
Has a sleep between 1pm and 3pm (if she's not awake by 3.30pm I go and wake her up)
Goes to bed at night between 7.00-7.30pm

She also takes a while to fall asleep at times and talks and sings to herself but I know she isn't ready to drop her afternoon nap (I'm due the same time as you with #2 and REALLY need that down time).

We recently moved her out of the 'nursery' into her new room and her big girl bed. The new room is at the front of the house so gets a lot more light in the mornings - prior to this she was waking up between 8-8.30am and it was bliss! I miss my sleep ins!
