I agree - being out of the room is about the best option. I unfortunately waited too long to introduce a bottle with my first born, so he would only take breastmilk from me, ever, until he was 1 when I weaned him. He would take juice from a sippy cup, but he never liked cow's milk in a bottle or breastmilk. But when we did finally wean him, my husband had to be the one to give him a cup of juice or milk with me downstairs. It took a little time, but he eventually took the milk from the cup.
