If you have a bedtime routine that works, plz describe it

Ma

I’ve always breast fed my 6 month old to sleep. I didn’t mind it but lately it’s started taking hours to get her to sleep as well as taking too long to get her back to sleep during night feedings. If you have a system that works that doesn’t include breastfeeding or bottle to get baby to sleep, please describe it. I understand it will take some training and won’t happen overnight for us but I’m exhausted and we need a new routine. Thanks!
