Declan Docherty (born January 12, 2003) is the youngest and second son of Steven and the other stepson of Kerry, the younger half-brother of Nathaniel, Ryan and Jake, identical twin brother of David and the younger brother of Bryce.

He swears a lot and sometimes gets aggressive with David. Before Ryan goes on a rampage, Declan suddenly fell down the stairs that made him screams in pain.

He was 3 years old when he appeared on Supernanny and is now 15 in 2018.
