I agree with Heather and Magda that test weighing is not routinely done in Britain, though I have talked with midwives who want to recommend it to mothers who seem overly anxious about their milk supply, something I don't recommend. I don't like test weighing for many reasons, one being the inaccuracies of scales. I didn't find it helpful when my own baby was in SCBU (not test weighing, just the ordinary daily weighing) weighed on electronic scales that were supposed to be accurate and discovering sometimes as much as 20 grams difference in two weighings, seconds apart when the only change was the digital readout was set back to zero. I certainly would have found test weighing once my baby was home unacceptable. The one positive situation I know of where weighing was carried out before and after every feed over 48 hours was a baby with DeGeorge syndrone. The baby hadn't been able to feed after birth due to heart complications. After several operations the baby was well enough to breastfeed, but test weighing was required. To the mother's amazement this baby took two or three times as much milk as she had been able to express at the same times of day (double pumping with a fully automatic breast pump). The weighing meant that the baby had no supplements during that 48 hours and the mother had the confidence to know she could exclusively breastfeed her baby. The baby had been exclusively breastmilk fed until then. The baby continued to breastfeed for several years, through more operations and is now healthy.
