This is Emma Bond, 24, from Oswestry, Shropshire.
She posted a picture of her doing so to her Facebook profile. That day it was deleted.
She told MailOnline:
The original photo was only viewable by my friends and family. Everyone was aware it was touch and go, so I was sharing the special moment with people to show them how far she had come. It was a magical moment and to have it removed the same day for breaching nudity policies was really rubbing salt in the wound.
In protest, she re-uploaded it to a pro-breastfeeding group, whereupon it went viral.
She subsequently received messages of support from around the world.
As a result, Facebook has reinstated the picture, and updated its policy.
At the time, it told BuzzFeed News:
People come to Facebook to share experiences of the world around them and on occasion this may result in the sharing of content that some may find upsetting. While we do not allow content that directly encourages violence, we try to create a safe environment that balances people's desire to express themselves and in some cases condemn what they see.
Bond told MailOnline:
I see so many animal cruelty or beheading or child abuse images on Facebook and report them myself, but nothing gets done. But something as precious and natural as this is removed instead. I know they put the image back up but it shouldn't take thousands of people to make a stand for that to happen. I still haven't got an explanation or apology.
