Two figures in, a clear answer out. The exclusive pumping calculator uses baby’s age, baby’s age now, baby’s age when your stash is over, do you want to add a buffer?, number of feedings in a day, existing freezer stash (optional), milk pumped per day and baby’s weight to produce milk needed per day, you will stop pumping in… and milk needed per feeding, applying the standard relationship for this problem in the order the calculation actually needs it.
What Is the Exclusive Pumping Calculator?
The exclusive pumping calculator gives you an estimate of milk needed per day, you will stop pumping in... and milk needed per feeding based on baby's age, baby's age now, baby's age when your stash is over, do you want to add a buffer?, number of feedings in a day, existing freezer stash (optional), milk pumped per day and baby's weight.
It is a quick reference figure rather than a diagnosis, and it is most useful for tracking how a number moves over time rather than for interpreting a single reading.
How the Exclusive Pumping Estimate Is Worked Out
The calculation follows published reference relationships, so it is a reasonable approximation when the inputs are accurate. It assumes an average adult and does not account for individual variation.
If you are comparing two people, or the same person over a period of weeks, keep the method and the inputs identical. A change in the method can easily look like a change in the person.
What This Calculator Does Not Do
It does not diagnose anything, and it does not replace advice from a clinician. If a figure comes out at an extreme, or if it differs sharply from what you expect, that is a reason to speak to a professional rather than to adjust the inputs.
Nothing you type here is stored or sent anywhere. The whole calculation happens in your browser.
A Worked Example
Working through an example, with baby's age set to 60, baby's age now set to 10, baby's age when your stash is over set to 5, the calculator returns milk needed per day of 4.60133, and milk needed per day (milk drinked day) of 4.60133, and volume of milk needed of -123.00664. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out milk needed per day?
Enter baby's age, baby's age now, baby's age when your stash is over, do you want to add a buffer?, number of feedings in a day, existing freezer stash (optional), milk pumped per day and baby's weight. The calculator then works through the relationship and reports milk needed per day, you will stop pumping in... and milk needed per feeding.
What does the exclusive pumping actually calculate?
It takes baby's age, baby's age now, baby's age when your stash is over, do you want to add a buffer?, number of feedings in a day, existing freezer stash (optional), milk pumped per day and baby's weight and converts them into milk needed per day, you will stop pumping in... and milk needed per feeding using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter baby's age?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
