Christina Janice Heredia (née Laik) is the wife of Joe and mother of Brandon, Taylor, Samantha and Ryan.

A 9th and 11th grade English teacher and a perfectionist, Christina fears that people will judge her mothering skills and tried hard to impress her father. With the triplets, Christina had a hard time getting them to eat their meals and making sure they didn't wander off.

She was 43 years old at the time of her appearance on Supernanny and now she is 52 in 2017.
