Baby never sleeps!

LO is 6 weeks and never sleeps longer than an hour stretch. Today she only did 3 45 min naps all day. At night she will go back to sleep after waking but just doesn’t stay asleep. We have tried everything suggested and nothing helps. Just wondering if this is normal. I feel like she is not getting enough sleep(she is fussy a lot lately).

(Or if anyone has any suggested other than the common white noise, swaddling, dark room, etc. I am definitely open to suggestions)
