Enter baby's current stats
Use recent weight from your pediatrician or home scale.
Add typical feeds per day
Most breastfed babies nurse 8–12 times in the early months, dropping to 6–8 after introducing solids.
Use the range as a guide
Milk supply naturally adjusts. Utilize the range to plan pumping output or bottle prep.
Formula
Daily intake range (mL) = Weight (kg) × [guideline minimum, guideline maximum].

About Breast Milk Intake
Exclusively breastfed babies regulate their own intake. Pumping parents can use average volumes to plan storage and bottle preparation.
Signs baby is getting enough
During growth spurts (around 3, 6 weeks; 3, 6 months) babies may nurse more often temporarily to boost milk supply.
- 6+ wet diapers and 3–4 stools daily in the first months.
- Steady weight gain along growth curves.
- Baby feeds with bursts of sucking and swallowing, then seems satisfied.
Frequently Asked Questions
How much should I pump while at work?
Plan for the average per-feed amount times the number of feeds while you are away.
Why offer a range?
Breast milk volume varies with growth spurts, time of day, and infant appetite. A range provides flexibility.
My baby takes less than the average.
Some babies feed more frequently with smaller volumes. Monitor diaper counts and growth rather than focusing on ounces.
Can I overfeed with bottled breast milk?
Yes. Use paced bottle feeding and watch for cues to stop. Excess feeding may cause spit-up or discomfort.
Does milk intake change after starting solids?
Slightly. Breast milk remains the primary nutrition source during the first year; solids complement intake.
