"I felt so helpless and guilty," Starlyn Cafferata told "Good Morning America." "But the reunion felt amazing."
Cafferata and her husband, who are also parents to 2-year-old Zoë, documented their journey of becoming parents to quadruplets on TikTok after struggling with infertility.
Cafferata said while her babies stayed in St. David's Women's Center of Texas' neonatal intensive care unit, layers of ice and snow kept her from visiting them for eight days.
Once it was safe enough to travel, the Cafferatas were reunited with their four children.
Millions watched and commented as the moment unfolded in a video shared on the family's TikTok account.
"We are incredibly blessed that people care about our babies and are invested like we are," Starlyn Cafferata said.
Lennon and Francesca are now home. Stella and Enzo will soon follow.
Cafferata said said big sister Zoë is thrilled to finally meet her siblings.
