9 weeks old

My pediatrician said at my sons 2 month appointment yesterday his naps should never total more than 3hrs during the day and only be 20-30min long. Does this sound accurate?? He is only 9 weeks old. He naps anywhere from 35min-1hr stretches during the day about 6 times i thought that was normal? Now im being told to wake him. Its not like he has trouble sleeping at night he will sleep a full 6 hour stretch till his next feed. Help/thoughts? Does this sound accurate to start cutting his naps to only equal 3hrs total??
