I think Laurie is on to something. <it seems there was something about hypoglycemia? have mother eat a cracker or something prior to or during pumping? or a nourishing drink?> I would say start eating or drinking 10-20 minutes before pumping if possible to be sure digestion has time to elevate the blood sugar. :-)Still "employing myself" each morning to bring order out of chaos in my filing system. Just an hour ago I stopped to momentarily "skim" a complicated article, and when I read Laurie's post, knew just where to find it: Uvnas-Moberg K, Eriksson M. Breastfeeding: pjhysiological, endocrine and behavioural adapations caused by oxytocin and local neurogenic activity in the nipple and mmary gland. Acta Paediatr 1996;85:525-30. "The oxytocin-related elevation of glucagon and glucose levels makes maternal glucose available for transport to the mammary gland. Since the number of insulin receptors is increased in this area and decreased in other maternal energy stores, the suckling-related insulin release will cause a "suckling-dependent" transfer of glucose and possibly of other nutrients to the mammary gland." "The levels of gastrin and cholecystokinin (CCK) are raised . . . . ." Could also be responsible for the sleepiness. Jean *********** K.
