Ladies I need help

I just had my baby girl December 22nd it’s been only 4 days since she was born and the 24 I came home so I’m trying to see what I can do about baby fussing and the middle of night , sleeping all day ( got days and nights mixed up

Questions

1. How can I stop baby from fussing so much at night / early early morning ?

2. How can I build a sleeping schedule for her ? Or should I wait for her to get at least 1 month old because she going through a stage right now ?
