Pelphrey listed his favorite qualities he's seen in Cuoco, and shared his hopes that their daughter grows to be as "independent, talented, hilarious, generous, incredibly kind and thoughtful"

Tom Pelphrey is honoring his partner Kaley Cuoco on her 38th birthday!

In celebration of the Big Bang Theory alum turning another year older, Pelphrey, 41, shared a series of photos featuring the couple’s happiest days with their daughter Matilda in a tribute post to Instagram Thursday.

“Happy birthday to my fave,” he wrote in the caption. “Life has exploded into a million new dimensions since we first met, every one more beautiful and meaningful than the last.”

Alongside car selfies, family photos with their dogs and shots of Cuoco with their baby, he continued: “You are truly an amazing partner and an incredible mom. I can’t imagine Matilda having a greater role model to grow up emulating than her mom…. her independent, talented, hilarious, generous, incredibly kind and thoughtful mom.”

“So HAPPY BIRTHDAY from me and all the little ones. We love you!!!! ♥️💫🙏♥️💫🙏,” Pelphrey continued.

Since giving birth in March, Cuoco has shared several photos of Matilda on her Instagram. In April, the actress exclusively told PEOPLE about her life as a first-time mom and how "natural" Pelphrey is as a dad.

"I cannot believe how natural he is, how much he loves it," she gushed at the time. "I mean, when we were in the hospital, he did everything — every diaper, he's the swaddle king. All the nurses said, 'Oh my God, you're the best guy swaddler we've ever seen."
