Is my newborn sleeping too much?

She literally just eats and sleep. She’s 2 weeks old and she sleeps for sometimes 3-4hours at a time. I breastfeed and she gets full then knocks out again. She sleeps fine at night as well. Idk if that’s normal? FTM. She is pooping and peeing normal. She also like never cries. The only time she cries is if she gets cold when we’re changing her diaper. My mom says she just a good baby but idk? I feel like she sleeps too much
