ABCs, 123s and the birds and the bees? Most people anticipate two of these three subjects to be taught in kindergarten, but parents usually expect to take on the sex ed conversation on their own or much later in school.

While it may not be a class on intercourse, some parents are concerned that school is not the place to be learning about such personal matters, especially at such an early age.
