On the dr's scale, she weighed 7# 3 oz (naked). On my scale Friday
afternoon, she weighed 6# 12 oz (also naked). The dr has a mechanical baby scale;
I have a brand new Tanita BD-815U digital scale. Which is more likely to be
accurate? 7 oz is a huge discrepancy!
~~~ I find scales in pediatrician offices can give notoriously unreliable
readings. The mechanical scale in one local MD office registered a 5 ounce
difference between that and mine, when we moved baby from one to the other
within seconds. Pediatric scales can be old, used more often, failed to be
zeroed properly in a busy office, and babies are weighed at different times
during the GI "pathway" ( meaning baby may have just nursed, and not
urinated in a few hours, giving a higher weight, or baby had not nursed in 2
hours, and had just peed, and had a lower weight... things like that, so it's
hard to compare.) The only thing I trust when there are issues to tease
out, is my scale to my scale, same time in the feeding cycle ( like baby
naked, not having nursed in at least 90 minutes, and a recent diaper change if
needed). ( Or in rare cases of need, good digital scale mom rents to same
scale.) It's not perfect I know, but it's the better consistency than weight
taken during a ped visit, when we are looking at weights close together
especially. I also take time to weigh something that should register at a
known weight, like a teaspoon full of water, or a diaper I know should weigh
0.6 and see if it registers as expected, as a check.
Hope that helps with that part of the issue...
