Breast Milk Pumping Tracker

Production Volume

1. How does this pumping tracker work?

This tool functions entirely in your browser. Use the built-in timer during your session, input the volume from your left and right breasts, and hit save. The calculator instantly logs your daily total, updates your all-time analytics, and charts your production history to help you spot trends.

2. Will I lose my data if I refresh or close the page?

No! The tracker uses your device’s `localStorage` technology. Your data is instantly saved to your browser memory. You can safely refresh the page, close your tab, or reboot your phone, and your logs will remain intact. Note: Your data will only be erased if you manually clear your browser’s history and cache.

3. How can I save this tool as an App on my phone?

You can use this tracker just like a native app. On an iPhone (Safari), tap the “Share” icon at the bottom of the screen and select “Add to Home Screen”. On Android (Chrome), tap the three-line menu and select “Add to Home screen”. It will place an icon on your phone for immediate, full-screen access.

4. How often should I pump if I am exclusively pumping (EP)?

For a newborn (0-3 months), exclusively pumping mothers typically need to pump 8 to 10 times per 24 hours to establish and maintain a full milk supply. This mimics a newborn’s frequent feeding schedule. As your baby grows and your supply regulates, you can usually drop sessions safely, eventually settling between 4 to 6 pumps per day.

5. How long should a typical pumping session last?

A standard session lasts between 15 and 20 minutes, or until the milk flow stops. A common recommendation from lactation consultants is to continue pumping for about 2 minutes after the last drops of milk have emptied to signal your body to produce more milk.

6. What is “Power Pumping” and how does it help?

Power pumping is a technique designed to mimic a baby’s “cluster feeding” to rapidly increase milk supply. A typical power pump takes one hour: Pump for 20 minutes, rest for 10 minutes, pump for 10 minutes, rest for 10 minutes, and pump for a final 10 minutes. Tracking these long sessions is easy using our built-in timer.

7. How long is pumped breast milk good for?

Follow the CDC’s “Rule of 4s” for freshly expressed breast milk: It is safe at room temperature for up to 4 hours, safe in the refrigerator for up to 4 days, and best if used within 6 months in a standard freezer (acceptable up to 12 months in a deep freeze). Always manage your freezer stash by feeding the oldest milk first.

8. How does the freezer stash estimator calculate feeding days?

Our stash estimator uses the medical baseline that infants (between 1 and 6 months old) consume an average of 30 ounces of breastmilk per day. The calculator divides your total logged frozen stash by 30 to give you a reliable estimate of how many days you can exclusively feed your baby without needing to pump.
