At the end of the day, your baby being fed is most important.
But a new photo making the rounds online highlights the amazing power of breastmilk.
For her research project, Vicky Greene, a first-year Bioscience student, put breastmilk to the test and shared a picture of the results on Facebook.
“I'm a first-year Biosciences student and I'm doing this for my microbiology research project. The first sample(BmA)is from a mother feeding a 15 month old and the second(BmB) is from a mother feeding a 3 year old. I'm also doing colostrum in a couple of weeks,” Vicky explained.
She added: “So proud...here you have 9 Petri dishes containing the bacteria M. Luteus. The white spots in the middle are discs soaked in two samples of breastmilk. See the clear bit around the discs- that's where the proteins in the milk have killed off the bacteria!
“It also worked with E. coli and had a fairly good go at MRSA too....the future is bright, the future is breastmilk.”
Her post has been shared over 21,000 times and counting.
Many have expressed their amazement with the “interesting” experiment.
"Love this!" wrote one commenter.
Another added a simple: “Wow”.
Importantly, as another commenter points out: “The future is feeding your child, regardless."
