Dear Lyla, I tend to evaluate constipation at this age by weight gain.
Poor gain - constip. from poor intake, excellent gain - prob just early
example of "constip" we frequently see with bf. The bottles are a
confounding factor here and I can't believe that these twins haven't been
weighed since 5th day!! They needed a two week visit just for weight
check! (imho) Sincerely, Pat in SNJ
P.S. Hope they find them plump and not the other possibility.
