Back in May, Pelphrey spoke with PEOPLE about adjusting to parenthood as a first-time dad.

“It’s amazing. It’s heaven, it’s challenging at times,” he said. “It’s the most beautiful thing ever.”

“I’m so grateful to have a partner who I love to do it with because just two days with a baby in the house and I think of parents who are raising kids by themselves, and I don’t even understand how they do it,” Pelphrey then admitted. “My respect for single parents has gone through the roof.”

When asked what the most surprising thing about being a dad is, Pelphrey said, “It really has been surprising to me that it feels intuitive. There’s just something about how to hold her and how to burp her and intuiting what she wants sometimes when she’s upset.”
