How can I boost milk supply?
Well there are lots of ways: first of all, some people say that if the diet is not ideal then the milk will suffer CLICK HERE for more information about natural methods of increasing supply. That said, maternal diet seems to affect the mother's well-being more than the baby's, as the baby will get what it needs from the milk, which will be drawn from whatever the mother's body has available. It is certainly true that the mother needs to drink more, and eat well.
Secondly, there are Herbal Galactagogues - preparations which are thought to boost milk production, including Milk Thistle, Fenugreek, and Nettle Tea. Oatmeal is supposed to work too.
Thirdly, pumping (expressing) when baby is not feeding will work too.
Fourthly, there are medications which may help: read Kath's Story and Charlie's Story for more info on how two women managed to relactate using a combination of the herbal galactagogues, pumping, and over-the-counter drugs which boost prolactin levels in women.
Motilium, Domperidone or metoclopramide are often used to increase milk supply. Domperidone and metoclopramide work by increasing the prolactin level (the hormone which stimulates milk to be made. It can be used to increase a poor supply, e.g. after a long period of expressing for a premature baby but should only be used after trying increased frequency of feeding and skin-to-skin contact. It is taken three times a day for one week then the supply should be reassessed. If the supply is still low it may be worth continuing for another week. It is not appropriate if the baby is poorly positioned at the breast or is not feeding frequently enough to stimulate the milk supply. Metoclopramide (Maxolon) is less often used now because of extra-pyramidal side effects. Domperidone (Motilium) is safe enough to be sold over the counter for feelings of bloatedness.
