Mia June Swift is the youngest child of Jenny and Tony, granddaughter of Gloria and youngest sister to Jack, Joshua, Sean and Max.

Mia appeared to be a nice, happy, active and curious baby. She was often put in harm's way due to her older brothers constantly leaving the door open and her parents lackadaisical attitude towards baby-proofing.

She was only 9 months old when she appeared on Supernanny, and, as of 2017, she is now 7 years old.
