Transitioning baby to formula


Baby is 10 months old, think I’m going to start incorporating some formula every so often into her diet so I don’t have to pump so often, maybe just a couple formula bottles a week

I have a feeling she will not like formula though. She does pretty good with liking new foods though but not other drinks. She drinks pumped milk from bottles while I work, so she is used to a bottle, but anytime we put anything other than milk in the bottle (water, apple juice mixed with water per pediatricians recommendation when she was constipated), she will reject the bottle and throw it!

Is there an easy way to transition her to some formula every so often? As I mentioned, she will for the most part be drinking breastmilk so I was kind of wondering if at first I should do half milk, half formula? Any other ideas or tips to make for an easy transition?
