OKay this has been my on going battle with Amelia for a good few weeks now. I'm trying to get her to take a bottle of expressed milk and we're sort of getting there. I've tried numerous brands of bottles... the only ONE that she will take is a Tommee Tippee Closer To Nature bottle.
Closer to Nature® Anti-Colic Plus Bottles (pk 2)
I would suggest someone that isn't you tries to introduce the bottle. Gavin will smell the milk on you and will automatically want to take from you instead of the bottle. Also, pick a time when he's not upset, not hungry and not sleepy. I discovered any of those of a combination makes it far from an easy task. If the best time to try him isn't went someone else is around then I would suggest folding a bath towel several times and putting it between you both to block the smell from him.
I hope you have some success soon because I know myself how frustrating it is to try to get them to accept a bottle. Believe me, it's better to be persistant and keep trying. I tried, gave in, tried, gave in more times than I can count and now at 8 months I can't leave Amelia with anyone, she insists on me being the only one to give her comfort when she is upset or distressed or tired.
Good luck and keep me updated or PM me if you need anything.
