Kate Irene Gosselin is one of five children. She has three sisters and a brother. Jonathan Gosselin is the middle child of three boys. The couple met on October 5, 1997 at a picnic. They were married on June 12, 1999.
The Gosselins' desire to start a family was met with infertility. Kate underwent medical testing and was diagnosed with polycystic ovary syndrome. The couple turned to fertility treatments and immediately began intrauterine insemination. By February 2000, Kate was pregnant with twins. On October 8, 2000, Cara Nicole and Madelyn "Mady" Kate Gosselin were born, six minutes apart.
They began thinking of having another child and, according to Kate, a biracial infant of a teenage girl became available to adopt while Kate was an obstetrics nurse. They decided not to adopt the baby, but instead returned to fertility treatment. By October, Kate was again pregnant. Five weeks later (after being hospitalized for over-stimulated ovaries), at the initial ultrasound, the doctor announced that there were six sacs with seven yolks (embryos). According to Kate, this was very emotional news for them. The doctor suggested selective reduction, but the couple was strongly against doing so.
The sextuplets were born on May 10, 2004 at Penn State Milton S. Hershey Medical Center in Hershey, Pennsylvania. All six children were delivered within a span of three minutes with more than fifty doctors, nurses, and other specialists involved. Since the sextuplets were born in Hershey, they were called "Hershey Kisses" by the nurses and doctors who delivered them. In late 2008, the family moved from their Elizabethtown, Pennsylvania home to a larger residence in Wernersville, Pennsylvania in order to accommodate their large family.
