How do babies get more ****** milk as they grow?

andaloosa asked:


I know about increasing ****** milk supply, but what I wonder is how do the babies get more milk as they get older? Do they start drinking longer? Does more milk come out at a time? With ******* on bottles, there are more and/or larger holes – is that how it works with the ******?
I am exclusively ****** feeding my 2 month old daughter and am just curious. Thanks!
