Often babies won't take bottles from their mamas so it may just be that. I wouldn't presume to call you selfish since I don't know you at all but can I suggest a few alternatives?
Instead of leaving your dd with her grandparents for the wedding, could you:
-bring her with you and have her in a sling? (there are some fabulous fancy slik slings out there!)
-bring her with you and have dp (if you have one) hold her in a sling/carrier so that you're available to her but get a break from being the one in charge, iykwim?
-bring the grandparents to the wedding site and have them babysit there so you're available for nursing?
If you decide to not go with any of those options, I would skip the bottle entirely and get the grandparents to feed her with a cup (soft sided shot glass type would be best), a spoon, a syringe or medicine dropper.
I hope you find something that will work for you and your daughter
