My girls still sleep like this and they are 3. They would sleep 10-12hrs a night and still take 2,2hr naps. I too was concerned since my son NEVER slept. He didn't sleep thru the night til he was over a year old and he never took consistent naps, even as a newborn. But now I know that I'm just blessed!!! Most mornings they get up around 9:30am but there are still mornings(like yesterday) where they will sleep til 10 or 11am. So don't worry just enjoy it.
