Sleep help

Let me start by saying my baby is 5 days old, so I know she’s new and sleep training/cry it out method isn’t really an option.

My baby won’t sleep unless she’s being held. It was like that in the hospital too. I would feed her, she would start falling asleep or be totally asleep and I’d lay her down and she’d walk right back up crying. We have a sleeper we started using today and so far she sleeps okay in it, but she won’t sleep in her crib still. What can I do to get her to sleep in her crib? I don’t want her to get used to sleeping in the sleeper, but idk what to do!
