How Mom Will Tell 'Mono Mono' Twins Apart: Nail Polish Jenna and Jillian Thistlethwaite are finally home By Newser Editors and Wire Services Posted Jun 9, 2014 12:37 PM CDT 8 comments Comments In this May 9, 2014 photo, Sarah Thistlethwaite holds her twin daughters, Jenna and Jillian, after her delivery of the monoamniotic twin girls at Akron General Hospital in Akron, Ohio. (ED SUBA JR.) (Newser) – A set of rare "mono mono" twins photographed holding hands moments after they were born are home in time for Father's Day. Jenna and Jillian Thistlethwaite were born at 33 weeks on May 9 sharing an amniotic sac and placenta at Akron General Medical Center in Ohio. Jenna was born at 4 pounds, 2 ounces, with Jillian following less than a minute later at 3 pounds, 13 ounces. The twins spent nearly a month in the hospital's neonatal intensive care unit gaining weight and getting stronger. At nearly 6 pounds now, they were cleared to be released from the hospital on Saturday and went home with their parents Sarah and Bill and their big brother, 15-month-old Jaxon. "It's just nice to have everyone under the same roof," Sarah Thistlethwaite tells the AP. Thistlethwaite, a 32-year-old eighth-grade teacher, says she's already noticed a unique bond between the twins. "When I try to feed them on the feeding pillow, they gradually migrate toward each other," she says. "And when I lay them on the floor, they scoot toward each other. It's pretty cool to see them doing." Thistlethwaite adds that she's grateful that her and her husband's biggest worry now is telling the twins apart. She plans to solve that problem with pink nail polish for one and purple for the other.
