Nancy, Without seeing and being there, this is a toughie. You are sure that the baby doesn't have a bubble palate? I've seen this behavior with them. Did this problem originate at birth, or more recently? Any aggressive suctioning after birth? Any possibility that it is partly associated with a strong MER? The one thought crossing my mind is that maybe this baby could benefit from self-latching, ala the tub rebirthing. I'm not thinking that mom and baby need to go into the bath, but maybe mom could try reclining and placing baby on top of her, like they do in the Deliver Self-Attachment video, and allow baby to latch herself on; this might minimize touching of baby's head. If the mom's milk flow is very strong, this could also aid such a problem by utilizing gravity to help baby cope with the flow. I realize that the extreme sensitivity to stimulation may be more significant than what I am suggesting; I wish I could see this firsthand. My one other thought is that if the baby arches a lot, is she nursing in a flexed, supported position, or is she "hanging off" the lap? Sometimes lack of flexion can be an issue, too.
