(Cover) - EN Showbiz - Kristin Cavallari was surprised to learn that she didn't "walk around like a zombie" following the birth of her baby boy.

The reality TV star and her fianc Jay Cutler welcomed their son Camden into the world in early August.

Initially Kristin believed that she would be depressed and tired for the first few weeks following delivery.

"I set myself up for postpartum to be incredibly difficult and thought I would be walking around like a zombie," Kristin told Parenting magazine.

"I actually had this adrenaline the first few weeks, which made me not need much sleep. Every time I tried to nap during the day I wasn't able to."

Kristin is approaching parenthood with a very positive attitude.

The star relies on her loved ones to help her through tasks.

"[Motherhood] felt very natural to me," she said.

"You just have to go into it knowing you won't be getting much sleep and there will be hard times, but try to get help from family and friends. Don't plan on doing anything else those first few weeks." (C) Cover Media
