Check Out This Amazing Image of Breast Milk in a Petri Dish

You’ve suffered through bleeding nipples, leaky breasts and a baby who’s mistaken your boobs for a teething ring and wondered, was it worth it?

This now-viral image should serve as your answer.

The amazing photo, posted on Facebook by Vicky Greene, a first-year biosciences student at South Devon College in Paignton, England, shows nine Petri dishes containing the bacteria M. Luteus. Greene added breast milk samples to each of the Petri dishes — some with breast milk from the mom of a 15-month-old, and others with breast milk from the mom of a three-year-old.

In case you missed it, here’s the really cool part: the perimeter of each Petri dish is filled with bacteria, but in the center, where the breast milk was placed, the bacteria is completely gone, killed off by the breast milk.

As Greene explained in her post, “The white spots in the middle are discs soaked in two samples of breast milk. See the clear bit around the discs — that’s where the proteins in the milk have killed off the bacteria!”

Since the photo was posted, it has been liked 21K times, and shared more than 28K times. And it’s no wonder — although it’s nice to be told about breastfeeding advantages such as lowering your baby’s risk of having asthma or allergies, it’s even cooler to see clear photographic evidence of its benefits.

Greene also shared that for her next experiment, she is going to use colostrum (the yellow-colored, antibody-filled milk that a baby gets at birth, before mom’s milk fully comes in). She also noted that she’s already done this same experiment with e. Coli and MRSA bacteria, showing similar results.

See, Mom? Those milk-stained shirts were totally worth it!
