Little Brian Liddle jnr is the heaviest baby born at the Mercy Hospital for Women in Heidelberg though his parents never expect him to be that big.
Mother-of-four Natasha Corrigan says she wanted a "big, chubby baby" but she didn't expect one so big!
With only gas for pain relief, Natasha started to panic when her baby's shoulder became stuck during birth.
'I'm very glad he came out safely," she said, adding that she was grateful to have her partner Brian and sister by her side.
Brian jnr doesn't fit newborn nappies and the clothes his parents took to the hospital.
