M.B.
I would say that is pretty normal. All children are different though. Does she eat good? Is everything else normal? If so, I wouldn't worry. My son used to sleep from 9:30-7:30 and then took a nap from 9:30-noon and then again from 2:00-4:00. He didn't stop this schedule until he was almost 15 months old. I would say, enjoy the peace time:-))
Good luck.
