Does soya milk help to boost milk supply?

Like what Idza and Diana have mentioned, soy milk is healthy and has a number of benefits for the nursing mother. It is also believed to be a good milk booster for some. The only thing to note is that soy may cause phlegm in babies and it also contains phyto estrogens, which may affect hormonal levels. It is best that you start with a small amount first and monitor to see if your baby has any reaction to it. (mentioned in this article: http://sg.theasianparent.com/breastfeeding-diet-faq/) If you are looking to increase your supply, it is crucial that you are drinking plenty of water, having enough calories from well balanced diet, and getting enough rest. If schedule permits, pump more (pump in between feedings, increased demand would aid in increasing supply). These are more direct ways recommended by most to help increase supply.
