When to start drinking coconut water?

You seem to have answered your own question! :) Coconut water is usually consumed in the last trimester of pregnancy, but there are no disadvantages of consuming it earlier as long as it is taken in moderation. It is believed that coconut water helps to cleanse the foetus. I drank coconut water and my baby came out very clean. http://www.babycenter.in/x1019315/what-are-the-benefits-of-drinking-coconut-water-during-pregnancy
