Diane - I think that weighing wet disposable nappies (diapers) on the
kitchen scales is a good idea if mom is really not sure if the baby is
voiding. I've been suggesting it for years! If urine output is scanty
enough though it will be yellow, or even pink, and easily seen. If urine
output is good, and thus clear, the nappies will be noticeably heavier than
unused nappies.
I have a South African paediatric textbook, "The Newborn Baby" by Harrison,
Keet, Shore which states on p 326, "Urine. Output. The bladder contains 5
- 40 ml of urine at birth which is voided within 24 hours by 90% of babies.
The daily output gradually increases to 1 - 2 ml/kg/hour and by the end of
the first week up to 10 wet napkins are changed each day."
Thinking hard here, (how Lactnet forces us to educate ourselves!). If
babies by about the 5th day of life are expected to take approx
150ml/kg/day, this equates to 6.25 ml/hour. That leaves a discrepancy of
4.25 - 5.25 ml/hour. What happens to this? Insensible water loss? (higher
in hot weather?) Stools? Or do we need to re-examine these figures?
