Melissa Kayser was heartbroken when she was forced to realize that she couldn't give birth – but luckily, her compassionate older sister volunteered to be her surrogate and bear her child.

The 33-year-old had endured nine miscarriages over the course of three years in her efforts to have children. After undergoing failed fertility treatments, doctors told her to find a surrogate.

"I couldn't stand watching Melissa go through loss after loss," Lisa told Inside Edition. "She hurt so badly and she just wanted a child so bad. If I could help give her a family, then I was going to do it."

After two of Melissa's embryos were implanted in her sister, Lisa successfully gave birth to twin girls named Ashlynn and Tierney who recently turned 6 weeks old.

Under Nebraska parenting laws, Melissa will be able to legally adopt the twins when they turn 6 months old. As for Lisa, she still doesn't want her own children and says she is content to be a fun-loving aunt, instead of a mother.
