Twins seem about as commonplace these days as kids named Aiden/Jayden/Brayden—there are two sets of twins in each of my daughters' grades—and that's with less than 60 kids per grade!

But over the weekend, Ohio mom Sarah Thistlethwaite gave birth to an unusual "mono mono" set of twins, named Jillian and Jenna, who join their big brother, Jaxon. "Mono mono" or monoamniotic twins share a placenta and amniotic sac—and only one in about 10,000 sets of twins does that.

The pair obviously got cozy during their time in the womb—they were born holding hands! In the Akron Journal, mom Sarah said that the twins were the best Mother's Day present ever. "They're already best friends." Sarah said. "I can't believe they were holding hands. That's amazing."

Cheers to the adorable family—and to the new "best friends," who will remain in the hospital for another couple of weeks to manage some breathing issues they have.
