A pumpkin for her pumpkin! Kristin Cavallari got fall started right by taking her 13-month-old son, Camden, to a local pumpkin patch in L.A. on Saturday, Oct. 5.

Dressed for the season in a gray sweater and slim-fitting olive-green pants by 3x1, the 26-year-old Hills alum carried Camden on her hip as she browsed the selection of autumn gourds. Her little one -- in a green T-shirt, jeans, and mini Converse -- had his hands full, too, with a pint-sized white pumpkin.

The mother-son duo, along with Cavallari's husband, Chicago Bears quarterback Jay Cutler, recently celebrated Camden's first birthday. And if the former Laguna Beach star has her way, they'll have more little ones to celebrate soon.

The fashion designer would like to have a second child "sooner rather than later," she told Us Weekly at her Junk Food Vintage NFL runway show on Sept. 10, three months after her wedding. "And I would love to have a little girl, but if I had another boy, that would be great, too."

Camden, she added, is already "a walking machine" and "trying really hard to talk" -- with some pretty sweet success! "He says 'Mom,' and that just melts my heart," she gushed. "It's amazing."
