Some babies will only take it if you don't look at them while you feed them ( strange I know). I had two breastfed babies I kept and no one could get them to take a bottle. Turns out the first one would if I fed her and stared the other way the whole time. I tried it again with another baby who had the same issue and it worked. I dunno if it was because I wasn't their mom and they knew it won't a boob or not but it worked. It's worth a try :)
