Breastfeeding & Bottle feeding

Who has there baby on a breastfeeding/bottle feeding routine? My daughter is six weeks and I’m breastfeeding her and bottle feeding her. I was bottle feed her at night and breastfeeding her during the day for like two weeks just so I could get some sleep. And my husband would feed her. However I fell out of the routine finding it easier to breastfeed her in the night so I don’t have to get out of bed and my husband could get sleep as well. But now I still breastfeed her in the day and bottle feed her throughout the day. And now I really don’t have a routine at. I also find her not even wanting her bottles sometimes at night and preferring to breastfeed. I want to have her in a constant routine. Any mamas out there struggling or have to put there baby in a routine?
