Explaining first right of refusal for children in Indiana

Someone queried with "explain first right of refusal for children in Indiana" to get here,  I do not know why the query did not lead them to two posts I have here on the Indiana Parenting Time Guidelines' right of first refusal. Those articles are:

• Parenting time - Right of First Refusal 
• Following Up on ""Parenting time - Right of First Refusal"

The bottom line is this:  if non-custodial parent is available to watch the children while the custodial parent has to work, then the non-custodial parent has a right of first refusal to watch the children.
