Brittany Mahomes is unable to comprehend the rapid rate at which her young son is maturing.

On Tuesday, the mother of two and co-owner of the Kansas City Current said on her Instagram Story that she was celebrating the birth of her son Patrick “Bronze” Lavon, who turned four months old.

A note that she added to one of the photographs said, “How are you already four months old?” The photograph depicted Bronze smiling at the camera while he was pushing himself up.

Afterwards, Mahomes, who is 27 years old, uploaded a picture of Bronze with his older sister, Sterling Skye, who is 2 years old. In the picture, the younger child is positioned against her, and she is holding a hand on his head while looking at it intently with a smile on her face.

“It seems like it was only yesterday when I was here. “However, when you’re having a good time, time seems to fly by,” she added.

In addition, the mother of two uploaded two photographs of her youngest child from the newborn shoot, annotating the final photograph with the phrase “ok, I’m done.”

Brittany shares her two kids with husband Patrick Mahomes, 27, who posed with his kids in a photoshoot the family shared last month.

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.

“Thanking God everyday for these 3🤎,” Brittany captioned the sweet shots, which began with a side-profile photo of the mom of two holding her infant son, who was swaddled tightly, as she looked down at him.
