How long does your one to two year old sleep?

My son is 13 months old. We have always been very structured at creating and sticking to a routine with his sleep habits and therefore is a very good sleeper. He takes 2 naps a day. 9am-1030/11 and then 1:30-300/330. Both naps are never on the long side together - he does one shorter and one longer but it flips. He goes to bed between 6-6:30 and sleeps until 6:30-7:00am. If we put him to bed later he still wakes up at the same time - it makes no difference.
