I’m always excited to read about good hard science that reveals more about the awesome power of women’s and babies’ bodies. Check out this article about the hundreds of different bacterial microorganisms that have been identified in breast milk through DNA sequencing.

In addition to the further confirmation that a mother’s milk can’t be duplicated in its richness and complexity, this article also lends support for minimizing interventions in labour where possible:

The type of labour also affects the microbiome within the breast milk: that of mothers who underwent a planned caesarean is different and not as rich in microorganisms as that of mothers who had a vaginal birth. However, when the caesarean is unplanned (intrapartum), milk composition is very similar to that of mothers who have a vaginal birth.

These results suggest that the hormonal state of the mother at the time of labour also plays a role: “The lack of signals of physiological stress, as well as hormonal signals specific to labour, could influence the microbial composition and diversity of breast milk,” state the authors.

Our bodies truly are amazing.
