Breastfeeding mom, tips and tricks to transition to cows milk.

I’m starting to transition LO to cows milk one bottle/sippy a day. My lo is 9 months doctor told me to do this. So far she isn’t a huge fan, I’ve tried heating it up in a bottle, in a sippy cup ,she’ll take a few sips and then not want any more does anyone have any tips or tricks or a similar experience and did your baby end up growing a liking to it?
