Righty here. Along with hubby and 3 out of 4 kids. The "baby" (he's 4 1/2 yo) is a lefty. Will be interesting teaching him to write.
My grandmother didn't believe me until she babysat him and the rest of the monkeys. He is a lefty. Eats. Writes. It's all left-handed. My hubby's twin brother is a lefty. And he has twin nieces and one is a lefty. So, I guess it runs in the family.
