Bedtime Routine

I've a 6 week old and I'm trying to start a bedtime routine for her. The tough part is that she sleeps after breastfeeding her, so I can't put her down in her bassinet before she goes to sleep. Also she has reflux so I try and keep her upright for a little while after I feed her. Now I started a bad habit and she's use my breast to sleep. Any suggestions on the bedtime routine?
