In a new interview with etalk the star reveals his baby "didn't change the dynamic."
Instead there's only more love!
"There's just more. There's more love, there's more diapers. There's more all that stuff, you know," the 40-year-old explained.
As for their bub's name, the Canadian-born actor didn't give her exact title away but said they were very happy with their choice.
He'd previously joked that he was going to name James Excalibur Anaconda Reynolds instead, and had tried to get the name over the line for baby number two.
"I had [suggested] the same name, except with all the letters in the name being silent, which again was confusing for everyone. Especially me. We settled on the right one," he joked.
Ryan says his first-born daughter James, who turns two this month, is a total pro at being a big sister.
"It was kind of profound. I just love watching my older daughter take care of the newborn. That's been kind of neat to see."
Being the only male in his family certainly doesn't bother Ryan. "I'm doing my part to wipe men off the face of the planet," he joked.
Earlier in the month, the Deadpool star confirmed the sex of his second child during an interview with Conan O’Brien.
“Two kids under two is tough,” he told the host of Conan, adding, “Yeah, a lot of estrogen. It’s like American Girl took a s—t on my life.”
