It was certainly the most precious moment of life for a couple in Pennsylvania when they saw their 24-week-old twin daughters sharing a kiss. Carrisa Gill and Randy had gone for a routine ultra sound of their babies when they witnessed the twins snuggling and appeared to be kissing in the mother's womb. The scan was done at the Fetal Vision Imaging in Pennsylvania last week. "Pregnancy is a beautiful thing to capture, especially when you get to see moments like this," Carissa told Fox 29. The couple has named their twins as Isabella and Callie. "It was hard not to be so thankful during this moment. I am so blessed and can't wait to meet our two precious princesses," she adds. The photos were posted on the Instagram page of the Fetal Vision Imaging center. The company uses new cutting edge 3D ultrasound, 4D ultrasound and HD ultrasound technology 'to bring images of your baby to life', according to their website.
