Tina lives in our building, in the apartment directly above ours. As Katie entered toddlerhood, she and Jen became "mommy friends," getting together to compare parenting notes and let the kids raise hell together. She has a 7-year-old daughter named Alyssa, who's all but adopted Katie as a pet, and also takes care of her 2-year-old niece Selena.

Born July 17, 1973 in San Francisco.
