Whoever intentionally solicits or causes any child to engage in an act of prostitution or establishes any child in a place of prostitution is guilty of a Class D felony.
Wis. Stat. § 948.08
Although colloquially referred to as prohibiting solicitation, this section also specifically, and alternatively, prohibits causing a child to practice prostitution. Cause is a substantial factor that need not be the first or sole cause of a child practicing prostitution. The habitual nature of the defendant's trading cocaine for sex with the child victim satisfied the requisite that the victim did "practice prostitution" with the defendant. State v. Payette, 2008 WI App 106, 313 Wis. 2d 39, 756 N.W.2d 423, 07-1192.
