Oral Sex in Preschool.

What would make these preschoolers do this sort of thing?

I think that these kids were either sexually abused or the saw it being done to someone. In the article it says."Young children are not developmentally prepared to engage in sex." This is saying that they are not prepared to have sex in anyway, so why were they caught having oral sex? For these kids to do that at a very young age is not acceptable. In this article it also says,"Their brains are not ready to absorb that kind of information." If their brains aren't ready for that kind of information, how would they know what they were doing was wrong and not to it again? There is no reason for those children to do what they did. At the age of two the parents can talk about the body and how different girls are from boys. this was said in this article, Allegations of preschool oral sex shock parents on CNN. So these children's parents should have told them what is wrong and what is right.
