Ciara and Russell Wilson's youngest child is celebrating a major milestone.

Their son, Win Harrison Wilson, just turned one year old, and Ciara marked the occasion with some never-before-seen photos on Instagram.

The singer shared a slideshow where we can see Win evolve during his first year of life. The series of photos include some gorgeous portraits of the toddler, as well as a selfie of him and mom Ciara. There is also an incredible video of Win playing Just Dance with Wilson.

Ciara captioned the post: “The BIG 1!! WINning today and Everyday! You are the cutest and sweetest baby boy! Always dancing, smiling, and laughing…Always all over the place! The worlds going to have to keep up! :) I’m so excited and grateful to be celebrating you today! I love you so much My little Prince #HappyBirthday WIN!”

After revealing the nickname "Little Prince," Ciara also gave her followers a peek at the baseball-themed birthday party the family threw for him. She showed her youngest in a personalized uniform that said "Rookie" and wrote, “Let’s Play Ball. The Big 1! Waiting for that 1st step like [eyes emoji]. Rookie Of The Year Party @DangeRussWilson #HappyBirthDay #WIN.”

In her following post, we could see that the rest of the family got uniforms to match. This slideshow offered a glimpse of Win's birthday cake and the rest of the party setup. Meanwhile, we got to see his older siblings, Future (7) and Sienna (4), singing "Happy Birthday" to their younger brother along with their parents.
