Newborn Feeding Amount
Newborns take roughly 150 mL per kilogram per day. A 4.5 kg baby feeding seven times a day takes about 96 mL per feed.
Your numbers
Per feed
96mL
Daily milk
675mL
Formula
Daily milk = Weight (kg) × 150, Per feed = Daily milk ÷ Feeds per day
Babies vary widely — if weight gain and nappy counts are normal, differing from this number is fine.

Frequently asked questions
Q. How is Newborn Feeding Amount calculated?
Daily milk = Weight (kg) × 150, Per feed = Daily milk ÷ Feeds per day — Newborns take roughly 150 mL per kilogram per day. A 4.5 kg baby feeding seven times a day takes about 96 mL per feed.
Q. Can you walk through an example?
With Weight (kg) 4.5, Feeds per day 7, the answer is Per feed 96mL.
Q. What do I need to enter?
Enter Weight (kg), Feeds per day. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Weight (kg) moves the answer to Weight (kg) 2.25 → Per feed (mL) 48 and Weight (kg) 9 → Per feed (mL) 193. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
Babies vary widely — if weight gain and nappy counts are normal, differing from this number is fine.
