Parker's birth quickly went viral after the Blacktown Midwifery Group’s Facebook Page shared the news.
“New record,” the post read.
“We are happy to report the not so little Parker and Mum Nikki are doing well. Welcome to the world Parker, you’ll be the talk of Blacktown Maternity for a long time to come.”
Despite Parker’s size Nikki praised all mum’s.
“I’m sure all births hurt, whether it’s 1.7kg of 5.7kg — they all hurt,” she told the publication.
