Naps during the day

How long does everyone's babies nap for during the day? My daughter is 7 weeks old and sleeps about 5hrs straight during the night, wakes for a feed and then sleeps for another 2-3hrs. During the day I can't seem to get her to sleep for longer than 30-60mins though. She hates the bassinet during the day and usually only sleeps if I'm holding her, if she's in the car or if I'm out and about and carrying her. Other than that she's a really easy going baby and hardly cries, but it's driving me crazy not being able to get anything done during the day! Any advice would be so welcome!!
