The 33-year-old was all smiles in the snapshot. "And just like that, she's 1," Katherine began her lengthy caption. "What a year and what a blessing she is. My little smiley baby that made me a mama of two girls."

Chris and Katherine also have a 2-year-old daughter together, named Lyla, and Chris has a 10-year-old son, Jack, from his previous marriage to actress Anna Faris.

Katherine gushed over her little girl

She added several emojis to her post as she continued to celebrate all of Eloise's wonderful traits. "She's pure joy, fun, and happiness," her caption continued. She's keeping up with her sister and having a blast. I can't believe she's already 1! I love you, Eloise!"

Fans quickly jumped into the comments to send their well wishes, too.

People sent the little girl plenty of love

"Happy birthday, sweet Eloise," one person wrote, before asking if the toddler found "the box and wrapping more interesting than the gifts," a common birthday experience among children her age.

Another person commented on how much Katherine resembles her mother, Maria Shriver. "You look just like your mom here," they wrote in part.

Katherine is among the growing number of celebrities who keep their children's lives pretty private

While the birthday post was definitely all about Eloise, the baby's face was carefully hidden from view in the shot. This has become a habit for Katherine, who likes to keep both of her girls out of the public eye. She isn't alone, either; fellow famous moms including Kristen Bell and Mila Kunis also keep their kids' faces off social media.

At this age, birthday parties can be pretty hit or miss — sometimes little ones find all the activity, excitement, and sweets a little overwhelming — so we're hoping that everything went smoothly for Eloise and her family.

Happy birthday, little one. We can't wait to watch you grow!
