Just wondering on average how much sleep your 3 yr old is getting? Are they still having a day time nap? How long are they sleeping overnight?

DD is sleeping for approx 2 hours during the day (usually 1pm to 3pm) and between 9 and 11 hours at night (bedtime between 7:30 and 9pm depending on whats going on and up again at around 6-6:30am)and i am wondering if this is ok, or should i be encouraging no day time sleep and sticking to bedtime rather than letting her have an extra hour or so up to spend with DF when he gets home.
