Brittany shares one daughter Sterling, with her husband, Patrick Mahomes, and they are expecting one more.

The athlete posted a side-by-side picture of herself cradling her bump.

The first was her pregnancy with their boy, and the second was with her daughter.

The difference in size was evident as her recent belly was noticeably bigger.

In anticipation of her due date, she took to Instagram to pen a sweet tribute to her one-year-old.

The former professional athlete credited her little girl for helping her learn the best things in life.

She mentioned that she could not wait for her to become a big sister and would not take life with her for granted.

The couple threw a jungle-themed baby shower to celebrate their little boy.

The decorations featured nude and white balloons and a life-sized giraffe.
