How to wean baby off ?🤦‍♀️

Ma

I don’t want to fully stop breastfeeding. I just want to know is there any way to make her take a bottle of expressed milk .she used to take a bottle of formula and expressed milk once a day since she was born but lately she doesn’t want no bottle at all ☹️ just would just take a bottle while in a car 🤦‍♀️ lately I been trying to give a bottle of expressed milk she would only suck for a couple milks Nd spit it out so now I have to throw the milk out 😭
