In December, the reality TV star opened up to Mini Magazine saying she had expected an “easy” labor because she was an athlete.
“It was the complete opposite of what I expected,” Bella said, referring to her delivery. “I was 10 days late and had to be induced. I thought I could labor naturally, but after nine hours, I couldn’t handle the pain.”
Bella said she pushed for three hours but couldn’t deliver her daughter.
“After 21 hours of labor, it ended in an emergency C-section. Birdie had a 14-inch head!” she said. “Even though it wasn’t the birth experience I had in mind, I’m so happy Birdie came into this world safely.”
On picking their first child’s name, the Total Divas star said it was simple from the start.
“My husband’s only request was that we name all of our children with B names,” she said. “His whole family are B’s and I’m a B, so he really wanted our kids to be B’s. From there, we wanted a nature-inspired name and that’s how we decided on Birdie. Her middle name is Joe after my grandfather who meant the world to me.”
