If given the option, most mothers would opt for pain medication and a quick birth, knowing that your baby is going to be bigger than normal.

But not Sydney mom, Nikki Bell. After being in labour for 2 and a half hours, she gave natural birth, with no pain relief, to little Parker Bell.

Weighing 5.75kg, he is one of the biggest babies staff at Blacktown Hospital had ever seen. The average weight for a newborn is 3.5kg, Women’s & Children’s divisional nurse manager Helen Konowec told nine.com.au.

Bell told the Daily Telegraph, despite her second child's size, she doesn't consider her efforts any different from other mothers: "I'm sure all births hurt, whether it's 1.7kg or 5.7kg - they all hurt," she said.

The proud parents are now hoping he will grow up to be a soccer player, and use his height to his advantage.

Little Parker Bell's arrival was announced on Facebook, where others compared him to much older babies.
