Bottle/cup dilemma

Kiara • ~🥰Momma to 2🥰~
I'm a SAHM and my DD is 7 months in a week and is EBF. I went back to work when she was 6 weeks, but only stayed for a few weeks. During this time she took the bottle completely fine. Since I've been home we haven't really been using the bottle, and now she won't take it at all. She will scream, cry, throw herself around and clamp her mouth shut. I normally wouldn't care, but since I'm returning to school in two months I would really like to be able to take a bottle, or a cup so she can go to a babysitter. Any tips to help her transition back to bottle, or sippy cup suggestions?
