I posted this privately to Pat, when I meant also to post it to the list: In regard to urine passed in the first 24 hours and possible related factors, many babies pee before they ever reach the scale to record the birth weight. So with these variables alone, comparing birth weight, (and figuring 10% of BW), and voiding pattern of a baby who has peed before weighing with a baby who hasn't yet peed is already a very inexact process. Plus how will we ever know how many pee and how much into the amniotic fluid during the stress of labor? AF is partially a product of the baby's peeing, and drinking it and peeing it again all during pregnancy, so analysis of amniotic fluid properties is out, even if any could be captured at birth. Has anyone ever proposed examining the placentas closely to find any correlation with fluid status of the mother and baby at birth? Fluids received by the mother in labor could not reach the baby's tissues without passing through the placenta. Is it possible to relate overhydration, normal hydration and dehydration to the condition of the afterbirth? Just musing. Jean ********** K.
