Patterson Caldwell previously opened up to PEOPLE about her past fertility struggles when trying to conceive Graham in 2017.

The 2004 all-around women's gymnastics champ said after a year of trying without getting pregnant, the couple decided to turn to a specialist for help.

After a miscarriage and two subsequent dilation and curettage surgeries, she eventually got pregnant with Graham after three rounds of intrauterine insemination (IUI), a fertility treatment that entails the direct placement of the male partner's sperm in the woman's uterus.

Sharing her 20-week update in October for her newest addition, Patterson Caldwell said on Instagram: "Grateful beyond words for a good report today and to be carrying another healthy, active, precious baby 😍 We're so excited for Baby C #3 to join our family 💗💙 #halfwaythere."
