Three months after my son was born I was just praying for the day I would get more than four hours of sleep at a time. Conversely, new mom Nicole Richie has created a jewelry line. Maybe this is what she thinks about during 3am feedings.

“It’s all costume jewelry," Nicole told People.com, of her new endeavor. "I like to play with jewelry and mix and match.”

Harlow's mom says she is working with “this really talented woman named Shelley Gibbs. She’s an artist and she sketches everything.” And that “everyone’s been really mellow and able to work around my schedule. If I need to go feed the baby, I do it.”

In addition to the jewels, Nicole plans on doing an infant and children’s clothing line, which will come out later this year as well. And, while boyfriend Joel Madden is enjoying his own clothing line success with DCMA, the rocker tells People.com that Nicole is downplaying her latest achievements, “She’s being modest," he boasted for her.

Awww. Maybe he's doing the 3am feedings?
