agree with Aradhana
i am completely agree with Aradhana even not ony water but other liquids also like lassi, juise, lemon water. The more liquid you intake there are less chances for urinary infection, which is a major problem in ladies.
As Aradhana suggest for Satavari powder, ther is also Starvex, which you can take with milk and it helpful in milk supply + tightening of brest.
Enjoy the motherhood
