Bottle advice.

My daughter is 8 month old and will be 9 months old when I leave for 4 days. She refuses the bottle and I am so stressed out about leaving her. Any advice on what I can do? Starting today I'm goin to be pumping two bottles a day and giving them to her (didn't go over well) also have my SO try and offer her it without me in the room. Will she starve if she doesn't eat the whole time I'm gone? Ugh I'm so stressed.
