Elizabeth Ann Boudreau

Father appeals from an order modifying a dissolution decree and increasing his child support obligation. We affirm as modified. The parties were divorced in May of 1982. There were two children of the marriage, James Michael Benitz (Michael), born September 6, 1975, and Julia Elizabeth Benitz (Julia), born July 25, 1977. Initially, mother was awarded custody of both children and $225.00 per month per child in child support. A subsequent modification order in April 1989 raised the child support to $420.00 per month per child.
