Patrick Mahomes’ newborn daughter, Golden Raye, as she celebrated her oldest daughter Sterling’s fourth birthday Thursday.

Brittany, who is married to the Kansas City Chiefs quarterback, shared an array of pictures of Sterling throughout the years on Instagram in honor of her daughter’s birthday.

In her post, she mentioned how Sterling was ‘the best big sister’ to newborn Golden and her brother, Bronze, two, and even shared a sweet photo of the four-year-old and her new sibling.

Golden was dressed in a light pink onesie and a white knit hat complete with a big bow on its front.

And, on her Instagram story Friday, Brittany included a video of Sterling pushing her little sister back and forth in a stroller, which was covered by a pink gauze blanket.

‘The best big sister,’ Brittany captioned the clip, adding a smiling emoji with tears in its eyes.

Golden was born on January 12, just a mere few weeks before her husband competed with the Chiefs against the Philadelphia Eagles in the Super Bowl.

They lost the game 40-22 to the Eagles, narrowly unable to make history with a ‘three-peat’ win.

Despite having just given birth, Brittany showed up to his subsequent games after the 12, including their divisional round against the Houston Texans.

The couple announced their daughter’s arrival on Instagram, posting a black-and-white photo of the two of them holding her tiny feet.

In the background, there was a wooden sign that read her name, ‘Golden Raye.’

And, now that the high school sweethearts have added to their brood, it looks like the family is extremely excited.

During an interview last March with SheKnows, Brittany gushed about how much she enjoyed being a mom.

‘Oh my goodness, I love being a mom,’ she shared with the outlet at the time. ‘I think I’ve been called to be a mom ever since I was little.’

‘Just seeing my kids grow up, and the things that they’re learning, and the things that they’re taking from their dad… when we have first experiences with them, taking them somewhere, seeing them happy and lit up and in good spirits when we do stuff, is probably the biggest thing that I enjoy,’ the former soccer player continued.

She also shared more about her daughter Sterling’s personality with the publication, explaining that the tot loves to be social.

‘Any type of activity with a playground involved is definitely her favorite thing,’ Brittany said.

‘Anywhere we go, it’s like, “I want to go to the neighborhood park! I want to go to this park with my friend!” She loves to hang out with her friends. So just getting out of the house, even going to, like, an indoor play area,’ Brittany added.
