Melanie Dudley, nursing her four-month-old child in a Mexican restaurant at the time, did just that – by placing a blanket over her head.
Kitty Yannone posted a snap of the mum, saying: “I love my daughter-in-law so much!!! Someone told her to ‘cover up’ while she was feeding my grandson #5 in a restaurant!!”
The image was shared more than 1,500 times but that was just the beginning.
Fellow Facebook user Carol Lockwood showed support for the image, generating a further 177,000 shares and close to 100,000 reactions.
“A friend’s daughter-in-law was told to ‘cover up’ while feeding her baby, so she did!” Ms Lockwood said in the post.
“I’ve never met her, but I think she’s AWESOME!!!
“I’m SO over people shaming women for nursing!!!
“PS: To reduce speculation: it was a man who asked her to cover up, it was 90 degrees and extremely humid, and, no, she wasn’t in a Muslim country disrespecting traditions.”
