The 35-year-old model appeared on Wednesday's episode of the podcast, Milk Drunk by Bobbie, and explained, "We're in full vasectomy mode. He's shooting blanks now. I don't have to be on a pill, thank God."
"It's so easy for them," she said of the procedure for males. "It really is. It's like the easiest thing. Justin went shopping with me right after."
"He was not laid up in bed," she continued, noting, however, that Ervin did ice the area.
Graham also shared how she and her husband have maintained such a strong bond since having children.
"Justin and I are really solid. We were able to be married for nine years before we started having kids. It really makes a difference," she said.
"For us, I was so glad that we were actually able to have the time to be able to spend with each other — so we got to know each other's everything — because you really still don't know each other's everything until you bring in kids. And then you get to know them on a whole other level, which is exciting and frightening and challenging all at the same time," she continued.
Mentioning that she and Ervin wake up early for prayer and meditation because it "grounds us and keeps us connected," Graham added. "We really value our marriage and our alone time."
