Hi. I was taught that the differential diagnosis of bright red blood in stools of newborns includes blood from mom's nipples. The reasoning explained to me by a Gastrointestinal specialist is that a newborn's enzymes aren't yet working to full capacity to digest the blood. So the question is, I suppose, when does a newborn/neonate/young infant attain that capacity? In other words, how old is too old to say it's blood from the mom's nipples? *********************************************** The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(TM) mailer for lightning fast mail delivery.
