AS2 'reverse' inheritance question

i’ve got an inheritance chain of AS2 classes set up where i have an array in the ‘child’ class that i’d like to be able to access from the ‘parent’ class:

bottomClass.as -‘parent’
topClass.as -‘child’

my question/dilemma is: how can the parent access the properties of a child class…is this even possible, or am i just looking at it wrong?

thanks,
