What is a good explanation for how the supplementation technique of = feeding tube devices work,with regards to how baby "knows how to take = less supplement from tubing and more from the breast"?Is this physics or = is it that baby sucks less from the tube itself when he is satiated more = from mom's milk flow. I've always wondered and keep forgetting to ask when I'm around other = LC's and lactation conferences. TIA always, Denise Ferrell,Indianapolis
