A common myth about breast milk is that the more water you drink, the better your supply will be, but that’s not the case. “Only increasing your fluids won’t do anything to your milk volume unless you’re removing it,” Zoppi said. Drink enough water to quench your thirst, but there’s no need to go overboard.
Hereof, does water intake affect breast milk supply?
Eating or drinking too little
Adequate hydration also is important for breast milk production. The amount of liquid you put into your body affects how much breast milk you can produce. I encourage women to carry a bottle of water for themselves in their diaper bag.
Consequently, how long does it take for breasts to refill with milk?
As mentioned, the breast is never completely empty, but milk flow is greatly reduced by nursing to the point where no significant amount is expressed. It typically takes 20-30 minutes to rebuild to an adequate flow and closer to an hour to rebuild to peak flow.
