Oh, OK so when the mother drops off the little 4yo at a friends for a sleep over, does she give a disclaimer to the other parent. "Uh, yeah, if she asks your teenager to perform cunnilingus on her, she's just asking her to explore her body. It's perfectly natural." That begs the question, what teenager wants to "explore" their 4yo sister's vagina?!

"The celebrated Doctor Spock said, 'It’s natural for young siblings to touch each other’s genitals. It’s better to gently discourage them than to use forceful speech or anger. It’s just a stage for most, and a perfectly normal aspect of mammalian behavior.'" Apparently, she lacks reading comprehension as well. This statement is in reference to young children of a similar age. It also says to discourage them.
