Why do "children's" authors insist on slipping in quite adult, leering and, wink wink incidents and conversations about, you know what?

"Wedded and bedded", in a children's book?
Be cautioned about Lynne Reid Banks' other offerings as well. They just slip this stuff in. Caught one in The Prince of Egypt.
