My 6 week old never naps!

She used to nap a couple times a day but the last week or so she maybe if I'm lucky does one nap unless she's taken on a walk or goes on a car ride. If she falls asleep it's only on me and when I put her down she wakes up ughhh. On top of it she's cluster feeding alllllll day and evening but sleeps well at night. I feel like I'm doing something wrong here. Can anyone relate!?? The baby center website says my baby should be napping 7 1/2 hours during the day lol yeah right!!!
