Dear Sue L., I would also be interested in seeing An argument against the existance of nipple confusion. The babies I see often get bottles in the hospital. With early discharge staff are frantic to get babies feeding early. They are sometimes too agressive with the babies, sometimes using Supplemental Feeding Systems. There is also a lot of concern about low glucose. They are testing babies and if they are below 40( could someone explain what these numbers mean) they insist on formula. Anyway I see a lot of babies who were breastfeeding well and then were given a bottle for some reason and then could not feed well at breast. The motion that the baby's mouth, tongue and lips do is completely different for bottle than breast. If it isn't nipple confusion, what is it? Marilee
