Every baby is different. My older daughter (24 now) was a great napper but she didn't sleep at night very well at all. She would take long naps twice a day for a long time. We were worried she wouldn't be able to stay awake for Kindergarten.... that's how much she liked her naps.
My younger daughter (14 now) was NOT a napper. She would take a 20 minute nap here and there but she slept through the night well, like your daughter. I never got much done when she was a baby, because she was constantly awake. But it sure was nice having her sleep through the night.
I didn't do anything different with the two of them.... other than the fact that I might have been more relaxed with my younger daughter because I was older.
Some kids just aren't nappers and some are. Some sleep through the night and some struggle with that. I think you should relax and try not to worry about it so much. If she's up during the day put her in a swing or bouncy seat so you can get some things done. Enjoy her! They aren't babies very long!
