I like Dr. Newman's suggestions. They are close to what I've been using. The really frustrating thing is that this important aspect is virtually untouched in the pediatric literature. I checked texts and did a lit search on medline and cinahl. Pooh. Lots of newborns void in the labor and delivery area before they are introduced to computer-age diapers. Check L&D forms-- some include a place to note voids but others don't. Seems like even a new person's kidney's should be putting out a few times a day from the get-go--even if it's concentrated. I still say those radiant warmers should be thoroughly investigated for the degree of water lossed via evaporation and the subsequent effect on urinary output. New soapbox--better get off...! Karen
