How long does/did your newborn (up to 8 weeks old) sleep uninterrupted in their bed overnight?

My 5 week old went from sleeping 2 hours in her bassinet in between each feeding all last week to now only sleeping 40 minutes before crying and demanding to be held. She will sleep for 2.5 hrs uninterrupted if being held. I don’t know why this has changed or what to do to fix it! I don’t want to bed share. I feel like everyone we have spoken to says their newborns always sleep for 3 hours uninterrupted in their own beds. Am I the only one who has an inconsistent baby? I feel like I’m doing something wrong or that everyone has good babies and I just got the short straw with mine 😩
