Maria Corry, from the US, posted the picture on Facebook, and it quickly became popular, with over 7,000 shares and more than 200 comments.
Explaining why she decided to cover up with a picture of a Victoria's Secret model, Maria said these are pictures people see everywhere and are okay with, whereas they can't handle a breastfeeding mum on their Facebook feed.
'So since my breastfeeding photo which showed NOTHING got reported more than FIVE times, I'm posting this. I bet this won't be reported, because you can see this picture in every mall you step into, huge and blown up outside the store', Maria wrote.
'This is not frowned upon, or ever reported, as it is seen everywhere. But a women nurturing and feeding their baby is looked down on. That is completely absurd!'
However, even when covering up her breast, the picture was still reported less than five minutes after it was posted, according to one of Maria's comments under the photo.
The young mum then went on to encourage other women like her to share their breastfeeding selfies, and to breastfeed their babies in public, in a bid change mentalities.
'Moms, post your breast selfies below. Nurse in public. People who think breastfeeding is nasty, or looked at sexually is a pedophile for even thinking of it in that way', she wrote. 'Breastfeeding is natural, it's what our breasts were meant for!'
Lots of mums did in fact post their breastfeeding selfie, echoing Maria's views on breastfeeding. Many also posted screenshots of the reports they received for sharing pictures of them breastfeeding their babies, proving just how many people complain to Facebook about such photos.
The mum also made an edit later on to clarify that her use of the word pedophile was because she was feeling 'angered' and 'hurt' that someone had reported her picture, but adding that 'anyone who sees breastfeeding as a sexual act, does have something wrong in their head'.
She also responded to people commenting against her BREAST IS BEST!' remark, saying: 'And yes, "fed is best" but it has been proven breastmilk is best for babies'.
Last year Facebook clarified its policy regarding 'Brelfies' (breastfeeding selfies), after mum Kaya Wright was wrongfully banned from a Facebook group for posting a photo of her breastfeeding her baby.
The official announcement from the social media site read: 'We restrict some images of female breasts if they include the nipple, but we always allow photos of women actively engaged in breastfeeding or showing breasts with post-mastectomy scarring.'
However, even though Facebook is okay with the photos so long as no nipples are on display, users are still reporting the images, which could show just how much of a taboo breastfeeding still is nowadays.
