Nicole Richie and her curly-haired cutie, 16-month-old Harlow Winter Kate, have fun at the farmer’s market on Sunday, walking alongside Joel Madden (not pictured) as he pushed his daughter’s toy car.

The family then made their way to lunch at the Four Seasons Hotel. Later in the afternoon, they headed out for a hike — sans Harlow — in the Hollywood Hills.

Nicole, 27, and Joel, 30, expect their second child in late August/early September.
