Erica Huston-Elem and Katelin Buchanan have been best friends since birth.
“Our mom’s were best friends! Her mom is my godmother … we grew up very much like family,” Huston-Elem, 34, tells PEOPLE. “We just grew up together like siblings. Our friendship has been more than a friendship, it’s a sisterhood. We’ve been there through all our life’s experiences.”
As the best friends grew older, they celebrated milestones and major life events together, like graduations and even marriage. Huston-Elem welcomed two children — now ages 7 and 4 — but for Buchanan, the road to motherhood proved to be difficult. She’s suffered several miscarriages and has gone through many unsuccessful rounds of in vitro fertilization (IVF).
