Patterson announced on Instagram in August that she and her husband of six years were expecting their second child, 10 months after the birth of their son Graham.

The athlete shared an image of the family of three outdoors, dressed in their best — including a “Big Brother” shirt for Graham. In one hand, the then-mom-to-be held a strip of ultrasound photos.

“We are so overwhelmed to announce that Graham is going to be a big brother and we are adding to our little family🤩,” she wrote in her caption on the post.

Patterson kept the sex of her second little one under wraps until delivery day, teasing alongside a family ultrasound-appointment photo on Jan. 10, “What’s baby #2 going to be?!?🙊”

Patterson previously opened up to PEOPLE following her 2017 pregnancy announcement about her and her husband’s struggle to conceive. The 2004 all-around women’s gymnastics champion said that after a year of trying without getting pregnant, the couple decided to turn to a specialist for help.

Following an initial round of fertility treatments, Patterson explained she got good news — but then ended up having a miscarriage and two subsequent dilation and curretage 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.

“Most of you know our fertility journey with Graham, but we are thanking the Lord that we did not have to go through the same thing for baby #2!” Patterson wrote in her August announcement post. “God likes to take our circumstances we think are impossible and says, ‘Just watch what I can do, nothing is impossible with me!’ I am in awe of His goodness!”
