Nia and Robert Tolbert of Waldorf, Maryland had a son six years ago. Then, four years later, they had identical TWIN boys. Well, Nia got pregnant again, and back in August they found out . . . it’s TRIPLETS. And they’re girls, which means they’ll have three boys and three girls. The odds of having one kid, then two, then three are about one in 1,000. Even though the idea of having triplets on TOP of three other kids sounds insane, Nia says she’s excited.
