specially concurring.
I agree with the result reached by the majority. I disagree with the rationale that the parents may bargain child support for visitation rights. Both child support and visitation are rights of and benefits for the child and should be carried out accordingly. In the absence of a contrary showing I believe the child’s best interest is deleteriously affected by the parent’s bargaining away these decretory rights. Cf. Anthony v. Anthony, 204 N.W.2d 829 (Iowa 1973); In Interest of K.J.K., 396 N.W.2d 370 (Iowa App.1986).
