Night Routine

I know it is incredibly early to get our little one into a night time routine, but at night our 6 week old seems to be the most unsettled and fussy. She seems hungry, gassy, over stimulated all in one! We have tried a calm warm bath, white noise, swaddling and feeding.

Has anyone had any success with settling your baby down at night or for bed? Any moms with older kids have advice if it just gets better with time?
