Wilmer Valderrama Marks Daughter Nakano's First Easter with Sweet Family Snaps: 'Little Miracle'
And Nakano looked too adorable in her Easter getup: a yellow onesie with a white bunny and black flower print on the front, complete with a pink headband atop her dark hair.
"You came into our lives as our little miracle, making your mother and I living under a brighter sky!" Valderrama, 41, addressed his baby girl in the caption. "Happy first Easter my sweet @nakanovalderrama, te amo por vida."

Baby Nakano was born on Feb. 15, which the new parents announced jointly on Instagram: "Life is an ever evolving journey, and for all those times when our path needs a light.. often angels are sent to show us the way and that we can be more ... straight out of heaven we welcome our first daughter."
The That '70s Show alum revealed his baby girl's name one month later during an exclusive conversation with PEOPLE, saying it "created an unbelievable debate in our family" as "some people thought it was off the wall, and others thought that it was just serendipitous and so beautiful."
As Valderrama explained, the name was inspired by a trip he and Pacheco took to Japan — a memorable sojourn that strengthened their relationship, and one that saw the pair exchange "I love yous" for the first time.
He also said when it came time to decide on a moniker for their baby on the way, he and Pacheco, a model, researched ancient Japanese warriors, ultimately finding the legend of Takeko Nakano, a female samurai.

"Nakano became something that felt strong, felt unique, felt different," the proud dad explained, adding, "I thought, 'What a cool, fun little conversation topic for our daughter to have as she grows older.' But also, the respect and the heritage, and the tribute to one of those beautiful moments where my fiancée and I said 'I love you' for the first time. To commemorate that trip to Japan with our first labor of love."
Reflecting on his journey to fatherhood, Valderrama said he feels as if he was "genetically built to be a dad," sharing that he was the one keeping track of ovulation apps and "counting all the days [and] windows" to conceive a child.
"Everybody talks about, 'I'll take the classes and do the podcast and learn more from other parents' and all that stuff. I kind of went in on it just more open-hearted and understanding and trusting that some things were going to wake up in me. And they did," he shared. "There was a very beautiful, primal and magical trait that woke up in me that just kind of engaged the moment that baby came."
"I don't feel any type of pressure or concerns or insecurities. They gave me the opportunity at the hospital to change her first diaper and I jumped at the opportunity to do it. It was a pleasure to change my baby's diaper! I kind of dove in," Valderrama added. "I just took the role and really, really was fascinated and excited to learn more about it."
