10 week old already sleeping through the night?

Brie • First time mommy living in OC! 😍🙆🏻💞
Is anyone else's LO already sleeping through the night? She is 10 weeks now and can sleep a full 8 hrs without waking. Is this normal? I'm still waking up at the times she USED to wake up. Wondering if I should wake her to feed or just keep letting her sleep till morning?
