2month old sleep

Just out of curiosity how much is your two month old sleeping throughout the 24 hour period day?

we try to put our son to bed around 6-9 pm everyday, and the pediatrician said he is in great percentage to let him sleep through the night and feed on demand instead of waking him up. i try to make his last feeding around 10-1 am but he will usually sleep until i wake him up and then he will usually sleep for 4-6 hours at a time in the night and wake up to feed twice but he will also take naps during the day. is he sleeping too much?
