Mary-- I'm not terribly comfortable with the idea of using test weighing, either, and was glad to see your posting on this topic. My understanding is that a test weigh (pre/post-feed weigh) is pretty useless unless done on an electronic scale, and unless done for every feeding over a period of time, although I know there are clinics where pre- and post-feed weighings are done pretty regularly. Perhaps in some settings useful data is obtained. My gut feeling is that this is more interventional than I like to work, and that it is very stressful for most mothers. I'm much more comfortable working with a mother and baby using observation, weight gain over a couple of days, supplementing or pumping/supplementing where I'm really worried, and looking at output. I am interested in hearing from the LCs who find test weighing a useful tool. I'm always open to learning new things.
