How To Boost Milk Supply

Been searching articles on how to boost my milk supply as it has not been very consistent! It may be enough now but I am not sure when I am back to work as for the time being, I am direct latching him whenever he needs me but when I am away, it will be difficult for me so the only solution will be pumping the milk out. But I could not find a proper article on the topic that I wanted, instead I found a lot on natural ways to boost testosterone !! Haha, well, guess I just have to stick to the document that that I got from the Breastfeed advocates!
