Baby won’t sleep in bassinet?!

ne

Hey ladies, my 1 week old LO won’t sleep in his bassinet at all. He will only sleep in someone’s arms, or in his boppy lounger, which i can’t do either at night! 😞 as soon as the lights go off, or if you place him in the bassinet he wakes up immediately and won’t stop screaming. How can i get him to sleep in his bassinet? I know sleep schedules can be messed up this early, but he will sleep if he’s held- so i know day/night confusion isn’t the issue right now☹️ help!
