baby naps

As
How many naps does baby have & how long do they sleep each nap? My sons is 9 months old on the 5th. He sleeps 11:30a-1:30p for morning nap & 3:30p to 4:30-5p second nap. Is that normal to sleep less during the day? Bedtime is 830-9 & sleeps til 8am. Anyone else have any suggestions about naps or nighttime? Trying to transition to own room.
