Donna Mihalik (born March 29, 1962) (née Santucci) is the mother of Blake, Cole, Aiden and Stephanie and the widow of Steve Mihalik.

After her son Cole survived a two-year battle with leukemia, her husband Steve suddenly died, leaving her to raise their four kids alone.

Because of her two oldest sons' bad behavior, she was emotionally depleted & found it easy to give in instead of disciplining.

Donna was 43 years old in 2007 of her appearance on Supernanny and as of 2018, she is 56 years old.
