So the other day I was at a fund raiser… A friend and I were talking, and her 5-year-old son was there. As we talked, he was minding his own business, playing with his toy cars. But then we heard his little voice – "Mommy, what is Planned Parenthood?"

Despite always being open with her child, I could see the panic set in. There could be a whole conversation behind that question before she ever got to an answer. Isn't it too soon for "The Talk?"

Perhaps not. As the organization SIECUS writes, "sexuality education is a lifelong process that begins at birth."

Still, a 5-year-old is in a different place than a teenager. And while there are great resources for parents who plan to have the talk with their adolescents, what about those parents with questioning preschoolers?

Fortunately, bestselling children's author Robie Harris is coming to the rescue – again – and much to the dismay of her critics, who have called her efforts "pornographic."

At the end of the month, "It's Not the Stork" will be available to help parents (aunts, uncles, godparents, and others with children in their lives) have "the talk." The colorful book is a sex-education resource written for children ages 4 and up.

A grandmother, Harris states, "When we answer our kids' questions in an honest straightforward way, they feel honored. And if we don't answer them, then we are saying that something is wrong with (their) question."

Other Harris books that are great for children and parents include "It's Perfectly Normal," geared for children around age 10, and "It's So Amazing" geared for boys and girls around age 7.
