Kristina works hard parenting her teenage girl and an autistic boy.
Kristina Anna Nicholas Braverman (Monica Potter) is Adam's wife, and a source of stability and support for anyone who needs it.[4] She is a typical soccer mom. Official material from NBC characterises her as a "wise and quietly forceful woman who loves her husband and children deeply and with incredible strength."[4] While she is always caring and nurturing, she can be high-strung and worrisome at times.
She goes back to work to support her family during her husband's unemployment, then quits, but goes back to work after Adam tells her that Rachel, his assistant at the recording studio, kissed him. She forgives him for this transgression, despite Adam's refusal to fire Rachel. Kristina constantly worries about Max, regarding his social deficits due to his Aspergers. She has shown her disapproval of her daughter's relationship with her alcoholic boyfriend, but eventually came around. She shaved her hair and was diagnosed with breast cancer in "Left Field" the second episode of season four."
She works on Bob Little's campaign for mayor of Berkley in season 3, but in season 5, a cancer free Kristina decides to run against Little for mayor. She leads a successful campaign with help from her manager Heather until she concedes the election.
According to Season 4, Episode 12 "Keep On Rowing," Kristina is 34 years old, which would mean that she gave birth to Haddie when she was only 16 years old. It is never discussed on the show if Kristina was a teenage mother, but it is unlikely since in season 5 she tells Amber that Adam proposed to her when they were in grad school. It is possible that she was lying about her age, but it may also have been an oversight of the show's makers.
