Screen Shot 2016-04-08 at 11.40.42 AMMany new moms often wonder if their newborn is getting enough of their breastmilk or formula. Although this article should not serve as a definitive factor on whether your baby needs more food or not, a lot of this worry can be remedied by having a more clear understanding of just how big a baby’s stomach actually is. You will often hear that a baby knows how much they need at any given moment, and this is very true.  The below are some common comparisons to a baby stomach size, and what that would equal in breastmilk or formula.  You may be surprised just how little they need at first. This is beneficial as some mothers do not get their milk right away, and knowing this information can make you feel a little more comfortable during your first days as a mother.

Milk Equivalent 5-7 ml (1-1.4 tsp)


Day 3

Growing quickly, your newborns stomach is now the size of a walnut. Although your babies stomach is growing quickly he still only needs a minimal amount of breastmilk/formula.

Milk Equivalent

22-27 ml (0.75-1 oz).


One Week

Milk Equivalent
