Marilee, Perhaps we should call it "nipple preference"? But I agree with you: the motion these babies do is more of a bottle suck, with pursed lips, on the breast, and if that isn't confusion, I don't know what is. Regarding glucose levels, Riordan & Auerbach's book has the best discussion of this that I have seen anywhere. It is actually discussed twice, in two different places, and among the notable information is the suggestion that 30 be the minimum level for the first 24 hours after birth. Look it up under "hypoglycemia-- infant". They also discuss and debunk the myth that glucose water is a good treatment..... -Lisa ****************************************************************************** Lisa A.
