Nicole is a busy mom

When Harlow Winter Kate falls asleep at night, busy mom Nicole Richie adheres to a rigid schedule of designing jewelry, dresses, shoes and accessories.
"I’m a busy mom, but there are 24 hours in the day, and I have a routine down so I can fit everything necessary into my life," Nicole tells PEOPLE at an event to launch her House of Harlow 1960 jewelry collection at the Fontainebleau Resort’s Ida and Harry boutique in Miami Beach.
Her jewelry — from about $30 for a ring to $115+ for a necklace — is a mix and match of bohemian, tribal, hippie and street-chic influences. "I started designing jewelry two years ago and can’t believe how much I love it," Nicole explains. "That is why I am expanding into other fashion which I love. I get a lot done late at night."

Nicole, 27, was joined by boyfriend Joel Madden of Good Charlotte at the event. The couple expect their second child in late summer.
