Refusing bottle at new daycare

Ooiiiiii where do I start... Emersyn is going to be 8 months on January 28th. She’s on the smaller side and between 13-14lbs and while I EBF when she was born until about 3 months, we started supplementing with formula. She also loves puréed foods since we started her at 4 months. From time to time she fights the bottle with me and other caretakers but I’ve learned she can’t have distractions and likes her bottles want when we give her one.. she still REFUSES bottles from daddy 🙈. At 5 months she started going to a babysitter that we LOVED and really took care of her. Unfortunately that babysitter got a job so we put her in a daycare center yesterday. Well she refused bottles all day, ate 1 jar of puréed food, and was fussy all day with them. Today I decided I’ll bring the bottles but also premade three 2oz of formula mixed with oatmeal and puréed peaches so she can get some formula in just in case.. glad I did because I called at noon and she still won’t take a bottle but ate 1 of the formula/oatmeals. I know it’ll take time to adjust I presume but this is KILLING me. I want her to eat especially since she’s so small. And not to mention the waste of formula 😓

Any tips?
