Brittany Mahomes and Patrick Mahomes welcomed their second 𝑏𝑎𝑏𝑦 in January, two months before their first wedding anniversary.

Brittany Mahomes can’t believe how fast her little guy is growing.

The Kansas City Current co-owner and mom of two took to her Instagram Story on Tuesday to celebrate as son Patrick “Bronze” Lavon turning to One years old.

How are you already one months old?” she captioned one of the shots, showing Bronze lifting himself up as he smiles at the camera.

Mahomes, 27, then shared a photo of Bronze with big sister Sterling Skye, 2, with the little one resting against her as she holds a hand on his head and looks at it closely with a smile on her face.

I feel like this was just yesterday. But hey, time flies when you’re having fun,” she wrote.

The mom of two also shared two snaps of her youngest from his new𝐛𝐨𝐫𝐧 shoot, writing, “ok I’m done,” on the last one.

Wearing neutrals and sitting on a bed, the Kansas City Chiefs star sat Sterling on his lap, then wrapped his arms around her to hold the infant, who was swaddled in a gauzy tan blanket.
