The age of the child is irrelevant except in cases when a very young child must use public transportation such as airline travel. If an order of visitation is in place the custodial parent must follow those guidelines set out by the court order. Failure to do so without "just cause" can result in the custodial parent being cited for contempt. The best option is to discuss the issue with a non-partisan individual such as a counselor, minister, and so forth. In lieu of an amicable solution either parent may petition the court for a modification of the original visitation order. If there is NO court ordered visitation established the custodial parent has the option of deciding when, where or if visitation will be allowed.
