โHow much milk do I leave when Iโm away from my baby?โ ๐ผ
If your babyโs nursing at the breast/chest at all, youโre not going to know exactly how many ounces theyโre taking. Thatโs normal and expected. We look at diapers, growth, and behavior, not food logs. โ
For most babies, the amount of milk they need in a day stays pretty steady from about 1โ6 months, then gradually shifts from 6โ12 months as solids do more of the work.
Newbornโ1 month: ๐ถ
Intake ramps up quickly in the first 1โ2 weeks
Around day 3, many babies take roughly 20โ30 mL (about 0.75โ1 oz) per feed
Around 2 weeks, lots of babies are closer to 60โ90 mL (2โ3 oz) per feed
Feeds are often 8โ12+ times in 24 hours
1โ6 months:
Most babies take about 25โ30 oz (750โ900 mL) in 24 hours
That amount is similar whether itโs breast milk or infant formula
Age and weight usually donโt change the volume as dramatically as people expect
Your body slightly adjusts the recipe of your milk
Formula-fed babies sometimes have bigger, more frequent bottles, but their 24-hour totalโs usually similar to breastfed babies
6โ12 months:
When solids start, milkโs still the main source of nutrition at first
As solids increase, milk usually decreases slowly
By the end of the first year, many babies take less milk than they did around 4โ5 months because more energyโs coming from food
If youโre planning bottles:
Start with your babyโs total daily intake (often 25โ30 oz in the early months)
Divide it across their usual number of feeds
Then adjust based on your babyโs cues, diapers, and growth
Your babyโs built to self-regulate. The โrightโ amount is the one that works for your baby, not what someone elseโs baby takes. ๐
