Breaking the mould

Posted by Kerry Sanchez on March 13, 2003

my Mum used to use the term to describe a child that looked like a parent or siblings that looked like each other. It woul make more sense if it was to describe a child or sibling that didn't look like a family member.

"they broke the mould when they made that one"

does anybody have any idea where this came from or what is the correct meaning?
