My mum was 56 when my nephew was born. She thought that was too young as she didn't have me until she was 30.
My MIL has just turned 61 so she would have been 54 when DD was born. SHe thought that was too old as she had DH at 22 and he didn't have DD1 until he was 32.
Funnily though my parents act much younger than DH's who have been 'old' forever.
