Allyson Silva is the daughter of Tom and the stepdaughter of Danielle, the full-blooded sister of Meghan and Brianna (who didn't appear on Supernanny), stepsister of Cheryl and MacKenzie, and the half-sister of Riley, Kassiah and Caden.
Like Cheryl, Mackenzie, and Riley, she was seen fighting, cussing, and name calling.
She was 7 years old in 2006. She is now 19 in 2017.
Sometime after "Supernanny", Allyson was diagnosed with Bipolar Disorder.
