does your 3 week old have a bed time/ sleep routine?

Does your 3 week old have a bed time routine or set bed time ? I'm really confused as Iv read about this on the web and can't for the life of me work out how anyone does it. My baby sleeps at different times everyday and can take ages to settle also he will wake up at varying intervals sometimes sleep for 3-4 hours sometimes 1-2 hours. I'm breast feeding and feed him when he's hungry with no set feeding hours. Am I doing something wrong?
