Breast milk is 87% water. Producing it pulls from your body's reserves — and your thirst signal often lags behind your actual need, especially in the early postpartum weeks. A personalized daily goal with smart reminders is the simplest thing you can do for your supply and your energy.
Why hydration matters for breastfeeding moms
Directly supports milk supply
Mild dehydration can reduce milk production. Staying consistently hydrated — not just guzzling when thirsty — keeps supply steady.
Faster postpartum recovery
Your body needs water to heal, reduce inflammation, and restore energy levels after delivery. Hydration is one of the most underrated recovery tools.
Reduces fatigue
New mom exhaustion is real, but dehydration makes it significantly worse. Even mild dehydration causes tiredness and brain fog.
Reduces engorgement discomfort
Adequate hydration helps regulate milk production rhythm, which can ease engorgement pain between feeds.

Common questions
How much water should I drink while breastfeeding?
Most guidelines recommend about 13 cups (104 fl oz) per day while breastfeeding, but your specific goal depends on your weight, activity, and climate. Thirsty Girls calculates a personalized number for you.
Will drinking more water increase my milk supply?
Dehydration can decrease supply. Staying adequately hydrated supports consistent production, but drinking excessive amounts beyond your goal doesn't further increase supply.
I forget to drink when I'm focused on the baby — can the app help?
Yes — smart reminders target the time windows where you most often skip drinking. You can also set a reminder tied to nursing sessions.
