breast to bottle nightmare.

My daughter is 5 months old and refuses to eat from a bottle. We came to the conclusion that she might be one of those babies that might just skip eating from a bottle and go straight to a sippy cup. We tried she still makes a fuss but gets more milk from a cup than a bottle. Do any moms out there have any advice or suggestions or some encouragement as to when or how this nightmare will end? I love breastfeeding her, I do... But It also makes it hard for hubby and I to leave her with a babysitter when she refuses to be fed by anyone other than me. thanks in advance. I will take any help I can get
