Tips on weaning

I’m 6 months pp and my baby mainly breastfeeds but will take bottles from anyone. We’ve gotten into a routine of me giving her a bottle every morning so she can have her vitamin D drops then for the rest of the day and overnight she nurses. We’ve also started solids for dinner time. On top of breastfeeding I will pump an additional 30 ounces a day since I over supply. I’m trying to get tips on how to start drying up my milk within the couple of months. We have plenty of frozen milk that will last her a few months after she’s weaned.
