Annie Nolan, 26, was frustrated with strangers asking her the same questions about her daughters - Delphine and Cheska - every time she left the house, and this was her solution.
"As a twin mum, you get asked a series of questions/hear a series of statements every time you go out."
The mother-of-two continued: "I know most people are coming from a great place and are just curious however many can be quite intrusive and after a while it's just plain exhausting.
"And since I was heading into the city, I knew the questions would be coming thick and fast... but I chickened out on the train and took them off!"
Since sharing the photo, which received more than 7,000 shares on her Facebook, Nolan was shocked to see that it had gone viral.
Writing on her Facebook page, she said: "You know that feeling when a little in-joke between friends turns international? Yeah, nah? Well that is what I am feeling at the moment!
"Hahahaha. Liam [her partner] leaves me for 4 days and his kids end up in the British news. Whoops!"
The mother has since received some negative feedback from the photo with people complaining she shouldn't be so rude.
One person commented: "Just answer questions you want to and say respectfully decline the rest. If I saw this sign (wait I just did) I'd think: man, what an unhappy don't-bother-me-but-look-at-me crabass. #getoveryourself."
Nolan addressed the negative feedback on Facebook, confirming that it was intended "for a laugh" and she did not walk around with the sign on the pram.
The blogger then posted a comical photo of her twins leaving the house with disguises after the photo had gone viral.
"Delphi and Cheska leaving the house for the first time since their 15mins of Facebook fame #delphiandcheska #twins" she wrote.
