Fiona-"if it ain't broke....don't fix it" is what I thought of for your mom with the small babe and weight gain that didn't satisfy her nurse. If baby's output was good, and nursing well, the 4-6 oz. gain was not great, but probably adequate. Interestingly, one of the discussions I am now watching on a net for NICU professionals is one on "demand" (read request ; ) feeding of premies, rather than the forced q3h feeds that we are all used to. Some brave souls in the NICU did a study of about 100 kids, and only 7 or 8 failed to gain well and do well with the demand protocol. Surprising? Not to some of us. Many MDs and nurses are reluctant (read insecure) to try this with a growing premie, when weight gain is so important, but I believe it will gain growing acceptance. It is hard for me as a neonatal nurse to do some things just on "trust", even tho I do such things as an LC! Denise Mollenkopf, RNC, IBCLC [log in to unmask]
