This same request was just posted on July 2nd. You might want to find that one and read those responses too. I tried to paste the link here, but it didn't work. Sorry. Anyway, here's the response that I had posted for that request:
I had this problem myself with my youngest. To tell you the truth, I got all sorts of horrible suggetions that just made me sick to my stomach - mostly, either let her scream for hours until she was so hungry that she finally took the bottle (my instincts told me "no way") and also just let her starve all day and feed her when I got home from work - it's been done before (but when I heard of all the "real" cases, these kids were eating solid food during that time). One lactation consultant that I went to promoted these kinds of ideas - I couldn't stomach it. However, I found another wonderful lactation consultant, who told me to try things from my heart. And that if it was making me sick to try things - that was Mother Nature's way of telling me I should not be doing it. This is what I did - and I'll be honest, I actually had to take an extra month of maternity leave because it took so long - which was a financial hardship to say the least. Anyway, this is what I did. First, I shopped for nipples that looked the most like my own physical anatomy. It is different for each person. Somewhere - I think maybe One Step Ahead - even used to sell a bottle that looked like a whole breast. (These didn't work for us, but they didn't really look like me anyway). Then, this is what I would do. I would put the nipple crack cream (what is that called? I can't even remember, it was 6 years ago - but it's like Vaseline sort of) on my nipple whenever she fed - so she sort of got that initial taste and texture. After doing that for a few days, I would put it on the bottle nipple and only at those times when she got drowsy and was practically asleep when she was feeding - I would do the "quick switch" - pull my breast out and stick the bottle in FAST. If she woke up too much and got all fussy, I'd quickly switch back. In the beginning, the bottle was probably only in her mouth for five seconds, eventually we worked up to maybe a minute. I just kept switching back and forth, until she was used to the sensation of it being in her mouth. Eventually, I worked my way up to maybe the bottle staying in for 1 minute and she'd take maybe 1 or 2 sips before she realized. I think around that point, I started working with the daycare provider - she was WONDERFUL. She let me visit with the baby (and my older child) and we'd hang out until it was feeding time. Then I'd breastfeed, try the "quick switch" - then hand her over to the daycare provider (who had been previously holding her, etc.). After probably 2 weeks of trying that, one day I left the scene, to see if she could get her to take a bottle if I wasn't around. She called me so excited - to say that while it wasn't much - she had taken 1/2 ounce from the bottle. It was then I knew that she would be fine, she could at least drink enough to hold off starvation, and that she really was only being stubborn. And truth-be-told it has proven true the rest of her life. She is both extremely shy AND the most stubborn-when-she-wants-to-be child I've ever met. Previous to this whole thing happening, I had been trying to give her a bottle occasionally, maybe once per week, and she had been willing to take it. Then we went on vacation, and when we came back, she refused to take the bottle. The "good" lactation consultant said it was the baby's way of controlling things and saying she didn't like change. I think that was true.
GOOD LUCK and try things FROM YOUR HEART!

Update - just wanted to say it just popped into my head what the nipple crack cream is - Lanolin (brand is Lansinoh, I think)!
