In 2009, the Massachusetts Child Support Guidelines added language acknowledging the increase in shared parenting by specifically defining how the Court should calculate child support differently when parents share parenting time "equally, or approximately equally."  The 2009 Guidelines recognized the sharing of parenting costs in shared parenting arrangements, determining the presumptive support amount "by calculating the child support guidelines twice, first with one parent as the Recipient, and second with the other parent as the Recipient.
