Divorce When can children decide not to visit a parent

I have an 11 year old and a 7 year old child that i share joint physical and legal custody with their mother. At what age, if any can, the child make the decision not to visit the other parent? I was under the impression children do not have any rights as such until they are 18 years of age.

Children do not have the right make the decision as to whether or not they will spend time with both of their parents until the are 18.
