This is probably not new to anyone, but just in case.... There is increasing evidence that continuing supply is less dependent on stimulation than on removal of milk. Milk seems to contain an 'autocrine inhibitor'. If one breast becomes engorged or is used infrequently,, the concentration of the inhibitor will increase and sends a message to the breast to cut down production. A bio feedback mechanism! Research continues at Hannah Research Institute here in Scotland. So, avoiding engorgement is important, and this is how mothers can feed from one breast only! You are all probably also aware of recent concerns re peanut allergies. In UK it is now suggested that the rise in these allergies seen in recent years may be due, at least in part, to peanut oils in baby milks, and also in nipple creams. They are sometimes listed as 'arachis oil' which few mothers here would recognise as peanut oil. Mary Broadfoot National Childbirth Trust Breastfeeding Counsellor Paisley Scotland
