I agree. What you're describing sounds like nipple confusion, which can only be really dealt with my stopping all artificial nipples, both bottles and pacifiers. Baby should be put to the breast as often as possible, and in between offered skin to skin contact as much as possible. If mom and baby get frustrated with latching, babe should be offered a supplement in some form that does not satisfy sucking urges, like a syringe or dropper or small spoon. Or a supplemental nursing system can be used to supplement directly at the breast. Until babe is nursing well, you should pump frequently to maintain your supply. Most young babies will return to the breast within a few days once rubber nipples are started. You're basically using the baby's strong sucking urge to return baby to the breast, by not satisfying it in any other way. Keep an eye on baby's weight gain, and supplement if necessary with pumped milk, but stop all rubber nipples.
I have fought nipple confusion with two of my three kids. Once, I lost, becasue I wasn't willing to get rid of the pacifier and bottles completely. DD1 wound up weaning before she was two months old and never breastfed exclusively, and it was heartbreaking. With DS, I tossed all the rubber nipples and used a syringe to feed him until he would latch again, and once he latched I used a supplemental nurser to teach him to suck efficiently at the breast. Anyway, he's going on 7 months and still EBF and is big and healthy and refuses bottles completely!
