Cole Garrett Mihalik (born January 8, 1999) is the second child of Donna and Steve, the younger brother of Blake and the older brother of Aiden and Stephanie.

He survived a two-year battle with leukemia.

Like Blake, Cole was very disrepectful to his mother, swore a lot, fought with his older brother, left the house without permission, and even gave his mother the finger. He was described as being very intense.

He refused to open his bedroom door and Donna took the knob off.

He was 8 years old in 2007 of his appearance on Supernanny and as of 2018, he is 19 years old.
