Aww. Bronx Mowgli Wentz is looking a little sleepy there. A trip to Borders with daddy Pete Wentz probably wasn’t the most exciting thing for a baby to do.

Daddy meant well though. Pete Wentz said he and Ashlee Simpson couldn’t be happier to have 7-month-old Bronx in their life. “The whole thing is a new adventure. Every day is a new milestone. He’s always discovering new things,” the Fall Out Boy bassist told In Touch at the AXE Instinct and Rolling Stone Magazine Present the Power of Leather event in New York.
