Katherine Heigl celebrated her son’s first birthday by reflecting on his birth in a touching post, where she revealed how “scared” she was as she brought him into the world.

In a series of photos that began with her standing shirtless and pregnant in front of window, she wrote, “At 9am one year ago today I had @joshbkelley take this photo of me so I could remember how incredibly pregnant I was right before we left for the hospital and my 12pm scheduled cesarean.”

“Joshua Jr had been in the breech position for over a month and had still not moved an inch a week before his due date so I made the decision to have a cesarean and was incredibly nervous and a little scared this time last year,” she continued.

Adding that she had “never been hospitalized or had ever had any kind of surgery and had no idea what to expect,” Heigl added that she was given morphine, they “numbed her up” and “opened her up”, and her difficult birthing process began.

“My doctor struggled to get him out because he was really wedged in there and not quite ready to leave the womb,” she went on. “When she finally pulled him out at exactly 12:33pm he didn’t start breathing and they worked quickly to get oxygen in him and start his tiny lungs. @joshbkelley was standing with them when he finally took his first breath. That day, as I slowly came out of the morphine haze and clutched my tiny man to me.”

In her series of photos, Heigl included snaps of herself smiling at the hospital as she held her son, and the little guy sleeping soundly in his father’s arms.

“I thanked the heavens for his breath, his life and for making me a mother three times over,” she continued. “As evening settled in Josh and I got cozy in my hospital room, found one of my all time favorites #SweetHomeAlabama on the tv and just relished in our perfect newborn son.”

“He was so tiny and new, so fragile and tender. As I lay him down to sleep that first night in his very appropriate 'welcome to the world' sleep sack I thought the moment would last forever,” she continued. “Yet here we are, a whole year later and it’s only the photos that remind me my brute of a boy was ever so new and small! Now he’s 26 pounds of rolling, tumbling, grasping, giggling, shouting, curious, jolly energy!”

“He is everything and more than I could have hoped for and he has brought our family even more joy, love, laughter, abundance, bliss and yes, exhaustion and exasperation too! It’s been a hell of a year and I could not be more grateful for it or him! Happy Birthday to my little man! Maybe I can make this next year go a little slower!'”

In addition to her baby boy, Heigl is also Mom to two adopted daughters Naleigh 8, and Adalaide, 4.
