When Babies eat organic baby food when they grow up, Do they have to keep eating organic foods?

My baby is 4 months old. My husband accidentally bought organic baby food(applesauce) and she LOVED it! BUT a couple of my friends say if she eats organic foods as a baby she will have to keep eating it when she grows up.

How do babies get more breast milk as they grow?

I know about increasing breast 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 nipples on bottles, there are more and/or larger holes – is that how it works with the breast?
I am exclusively breast feeding my 2 month old daughter and am just curious. Thanks!
