I second the Breastflow bottle. I introduced the bottle about a week too late to my little one and he outright refused. When I got the Breastflow bottle he did accept it. But then I got too cocky and left it alone for a while and now he refuses it again. I just gave up. I figure he'll go from breast to cup and that's that.
I read that if you introduce the bottle someone else should feed him, and in a different place than he's normally fed.
Also, I read that maybe formula in lieu of EBM might work since it's just a different taste and he might take it in a bottle. I didn't want to go down that road since I have more than enough milk for him in my breasts.
The Breastflow bottle can be bought at a few places - ToysR Us for sure, I don't think at Eugene, - I got mine at a local baby shop. But it's the same price everywhere, whether in the shop or the above website.
