That same month, Cuoco spoke exclusively to PEOPLE about her baby girl’s newest pastime. 

“We had a special saddle made for her, so it actually props her up. And she just sits in that thing and walks around and it is crazy," the 8 Simple Rules star said, adding that “we’re all there” to make sure Matilda safely used it. Although Cuoco told PEOPLE in a January 2024 interview that her favorite thing about her daughter is that "she finds me hilarious," she says Matilda is a complete "Daddy’s girl." 

In Pelphrey’s post, he wrote, "Happy 2nd birthday Matilda!! So grateful today for all of the incredible people that surround your life… all of the people who show up with love, laughter, kindness, joy, and encouragement. So grateful for your incredible mom. You make every part of my life better. Even drinking protein shakes.”
