Most parents think newborns need several ounces of milk at each feeding.
But on day one…
Your baby’s stomach only holds about a teaspoon.
About 5–7 mL.
That’s exactly why your body produces small amounts of colostrum in the first few days of life perfectly matched to your baby’s tiny stomach.
As your baby grows, their stomach capacity grows too:
Day 1 → 5–7 mL
Day 3 → 20–30 mL
1 Week → 40–60 mL
1 Month → 80–150 mL
According to current IBCLC guidelines, most breastfed babies take in about 25–30 oz of milk over a 24-hour period once milk supply is established.
Social media loves to show us pitchers of milk and huge freezer drawers over flowing with bags of frozen milk. These images coupled with the fact that you feel like you JUST FED THEM & now they’re hungry AGAIN can make you feel like your body isn’t making enough.
Since their stomachs are so small, and they are growing SO MUCH in the first few weeks they se to empty almost as fast as they fill.
THIS IS SO NORMAL
The reality is newborn babies thrive with:
• frequent feeds
• a responsive milk supply
• a mother who trusts the process
Your baby’s stomach is sooo small.
Your milk is perfectly designed for it.
And most of the time…
Their little body + your body is doing exactly what it was all made to do.
A rhythm of feeding .. emptying and feeding again .
In month 1 if you feel like all you do is nurse them, this is SO NORMAL!!
