Believe it or not, Sarah Stage just had a baby a few days ago.

The 30-year-old model posted a photo on Sunday showcasing her sleek physique and abs of steel just four days after giving birth to her first child.

“Total pregnancy weight gain was 28 lbs.,” the Costa Rican stunner shared on Instagram, alongside a photo of her donning a printed bra and “granny panties,” as she called her undies.

“I’m excited to resume my workouts in five weeks!” she added. (Although her body looks gym-ready as ever.)

The Los Angeles-based beauty made headlines with her unbelievably toned pregnancy figure and teensy baby bump. But Stage gave birth to a healthy son named James Hunter – 8 lbs.,7 oz. – on Tuesday.

“Love at first sight,” she wrote on Instagram with a snapshot of the newborn wearing a striped panda onesie.

The new mama also shared a sweet picture of her sleepy son Monday, with the caption, “#MilkDrunk.”

Over the weekend, the model-blogger showed off her nursery, complete with giant stuffed animals and a fuzzy area rug, with a photo of Stage cradling baby James.
