Large amounts of fluid are used especially when nursing. The Institute of Medicine recommends that pregnant women drink about 10 cups (2.3 liters) of fluids daily and women who breast-feed consume about 13 cups (3.1 liters ) of fluids a day.
The Institute of Medicine, an independent and non-profit scientific organization, says that men aged 19 and over should generally take in at least 3.7 liters of total water every day â about 15.6 cups a day. Women ages 19 and up should take in 2.7 liters of total water every day, which is about 11.4 cups a day. And if pregnant or breastfeeding, the recommendations go even higher, to 12.6 cups and 16 cups, respectively.
