Is there a way to have a parent child relationship built between 2 documents of the same type in the same index?

I used this example, but type is the same as my\_parent  
PUT my\_index  
{  
"mappings": {  
"my\_parent": {},  
"my\_child": {  
"\_parent": {  
"type": "my\_parent"  
}  
}  
}  
}  
I am trying to graph the relationships but it is only one direction as parent is specified and children are not.

The Data feed has this data  
{  
"id": "59cbde1446583e3f80010163",  
"parent": "59cab84446583e3f8000bb94",  
}
