Alexandra Breckenridge is a mom.

The former The Walking Dead actress and her husband Casey Neil Hooper welcomed their first child, a baby boy, on Saturday, Sept 3, her rep confirms to PEOPLE exclusively.

Son Jack Breckenridge Hooper arrived at 2 p.m., weighing 9 lbs., 1 oz. He measured 21 inches.

“When I first held my baby, the world melted away and I knew he was the most important thing I’d ever do,” Breckenridge tells PEOPLE.

After “a lot of research,” the first-time mom chose a natural water birth at a local hospital, where she was supported by a team of midwives and a doula.

“I had the benefit of being surrounded by experienced, loving women, while being overseen by medical staff, just in case,” she says. “Luckily, everything went beautifully and no interventions were needed. I couldn’t be happier with the experience. I’m definitely an advocate for water birth if you choose to go natural.”

And although the actress and Hooper, a guitarist for Katy Perry, had previously picked out their baby’s name, Breckenridge, 34, admits she had a change of heart.

“We had another name for him picked out before he was conceived, but while I was jet-lagged in London, maybe three months pregnant, I had a weird feeling his name was Jack,” she recalls. “I have no idea where it came from, but I just knew. The same way I knew that he was a boy. Call it mother’s intuition?!”

Breckenridge celebrated the pending arrival of her son during a quilt-themed baby shower in June, where she was joined by Walking Dead costar Alanna Masterson and her daughter Marlowe.

“It was so incredible to have all my favorite women come together to help make this adorable quilt for our son,” the mom-to-be told PEOPLE after the party.

What a beautiful baby…lovely name, as well. Congratulations to the new parents. She sounds as if she approached her labor with a bit of intelligence, too; no judgements about others choices either. Refreshing……
