'Meet our handsome little dude, due Sept. 2! It’s hard to believe it’s even real… Cause, WHEW, it’s been a process. infertility is hard,' she wrote. 

But the couple discovered Brooke suffered from secondary infertility when they wanted to expand their family. So they tried in vitro fertilisation.

'IVF is downright crazy,' Brooke dished. 'I’ve been a hormonal mess for several months, but it’s totally worth it, because it finally worked.' 

'Hallelujah! Yes! We are so happy, we are so thankful, Yes, I have a million thoughts and feelings about this journey, cause my heart is humbled and very tender for this struggle and the many women I’ve come to know through it.'
