Peter Hartlaub (pictured here in 1972) is the father of a 1-year-old boy named Theo. They live in Oakland and enjoy long walks at the zoo, discovering new child-friendly restaurants with mom and people who don't lie. Theo's first word was "da-da," which means when the kid steals the family car and smashes it into an ice cream truck, the worst grounding he'll get is no computer for a week. Peter is the Pop Culture Critic for the San Francisco Chronicle. Theo is training for a career in the field of competitive eating. You can follow him on Twitter @peterhartlaub.

Heather Maddan has a 2-year-old daughter named Sicily who was born on leap year and is expecting a second child due dangerously close to Halloween. She remembers the craziest part of becoming a mom at 26 was realizing that her friends were heading out in cabs when she was calling it a night. That, and having to carry around a bag that was bigger than her baby. When Heather and Sicily are not blowing bubbles in the park, or meeting friends for brunch, Sicily likes to go on Bay Area adventures with her dad or throw dance parties in the living room that put her uncoordinated mother to shame. They live in their native San Francisco.

Tanya Schevitz has a 3-year-old son named Cash Coltrane who has already acted in his own skit based on a Berenstain Bears story about a wild slumber party, who digs hot tubs in the sand (watch out ladies) and plays electric guitar like his Daddy. Unlike his mother, he only wears Lederhosen when pretending to be Governor Schwarzenegger on Halloween.

Tanya is the Chronicle's higher education reporter. Since uncovering a compensation scandal at the University of California, she has started a college fund for her son who obviously won't be able to attend a public university. She's only had to go to the emergency room once with Cash so far - when SHE got a concussion on the playground while pretending to be a lion.

Since becoming a first-time father in November, Delfin Vigil (pictured here at the old Serramonte Gemco portrait studios in 1975) has started wearing Old Spice aftershave and stopped believing bicycle helmets are dorky. His son Montgomery was named after the first street Delfin and Monty's mama, Tiffany, lived on together. The three live in the East Bay, have formed an air guitar band called "The Tummy Time Trio" and have a tour planned for the summer.
