If you need milk needed during the day and milk needed per feeding and you already have baby’s age, number of feedings in a day and baby’s weight, this calculator does the substitution for you. It suits a quick check, a homework answer you want to confirm, or any figure you need to sanity test.
What Is the Baby's Milk Intake Calculator?
The baby's milk intake calculator gives you an estimate of milk needed during the day and milk needed per feeding based on baby's age, number of feedings in a 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 Baby's Milk Intake 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, number of feedings in a day set to 10, baby's weight set to 5, the calculator returns milk needed during the day of 300, and milk needed per feeding of 30. 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 during the day?
Enter baby's age, number of feedings in a day and baby's weight. The calculator then works through the relationship and reports milk needed during the day and milk needed per feeding.
What does the baby's milk intake actually calculate?
It takes baby's age, number of feedings in a day and baby's weight and converts them into milk needed during the day 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.
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.
Can I use this for a quick estimate as well as a precise answer?
Yes. The calculator is built for quick checks, so round your inputs to a sensible number of significant figures and the result will be just as useful. If you need more precision, keep the same method and add digits to the inputs rather than adjusting the method itself.
