3 day old baby won’t stop crying

Hi.. please be kind with any comments made to this post.

I’m a first time mum & my 2 day old baby has continuously cry’s all day & night.

She feeds, has nappy checked & changed & burped but will still just cry no matter what you do.

Does anyone have any advice is this normal for a 3 day old baby or even some words or encouragement because I really need it.

Side note : I spent 2 nights with her in hospital after I had her & she was doing this and nurses & doctors didn’t seem overly concerned about it at all but I just feel so lost & overwhelmed
