My questions are: the posible child records, should be put in another table and establish a relation between table A and the new table or stay where they are and establish and a relation between both tables? In case, the second option is the right one (which I gues it is, for the updates, etc), what would happen if a child record could become in a child record for different parents? how could i deal with this?

To resolve a many-to-many relationship, you need a third table.
I will switch to Spanish now.
Ejemplo: En una factura aparecen varios productos. Un producto puede aparecer en muchas facturas.
Solución: crear una tercera tabla, que en este caso representa "detalles de factura" (adicional a la tabla de facturas).
