By now, Juliet Moody and Catherine Crowley are well used to being Youtube stars.
They went viral months ago when their satirical music video about breastfeeding, Ruin Your Day, took off in a big way.
The song, which poked fun of the anti-breastfeeding brigade, was an instant hit and Moody and Crowley, who perform as the band Sparrow-Folk, found themselves at the centre of media attention.
Now they've picked up another big spike of publicity after the British media noticed Ruin Your Day, which has racked up close to 600,000 hits on Youtube taking them towards a combined 1 million views on Youtube and Vimeo.
Moody said interest in the video had been incredible.
"It's been a bit like riding a wave, it dulls for a bit and then some other website or newspaper picks it up and we ride another wave," she said.
"We had a little wave in the Netherlands a little while ago."
In the last week the duo have done interviews with the BBC and with the Daily Mail and have been mentioned in an article in the Guardian.
Ruin Your Day was written after Moody grew tired of the dirty looks and muttered comments she got every time she fed her youngest child.
It was filmed in a local cafe and includes the immortal chorus, "everybody knows new mothers are exhibitionists, taking every chance they get to ruin your day with tits".
Sparrow Folk also sarcastically suggest the reason people are shocked by breastfeeding is because breasts are "dangerous and scary".
Their success has taken them by surprise.
"We're on the verge of hitting a million views combined between Vimeo and Youtube," Moody said. "When we first released the clip Cathy and I were looking at each other and saying 'Wouldn't it be awesome if we got 1000 hits?' After we went on the Today show we looked at each other and said, 'We might get 10,000.' "
But the hits simply serve to reinforce a serious message - that women have the right to breastfeed their children in public without harassment and without fear.
"The biggest thrill for us has been probably that it's been empowering for women ... for a certain group of people who could be the target of negative comments and attention," Moody said.
"One woman said to us 'The next time someone is rude to me [about breastfeeding] I'm going to sing that song.' It's such a thrill to think we've done that. It's probably made people aware of the situation who might not even have seen it as an issue. One lady told us she was breastfeeding sitting by Lake Burley Griffin, feeding her child, and an old man came along with his walking stick and said, 'You're not going to ruin our day are you?' and said, 'Good on you!'"
Good on them indeed.
