Came across this article (link is below) on The Conversation and thought it was worthy of sharing. The gist is that scientists are starting to study whether breast milk produced at certain times of day, contains "chrononutrition" like cortisol, melatonin etc. which help babies regulate their sleep patterns.

It's the first time I'd come across this concept, but it makes a lot of sense to me. Would be interested to know if anyone has come across similar articles or research, or even if anyone has anecdotal experience that backs this up?
