Event listeners in as2

Hello …
I have a movieClip inside a movieClip, and each is a button.

Once the parent MC has been clicked the child MC is revealed - to be clicked too. But because this child MC is nested inside the parent - the child cannot be clicked as it inherits its parents click functionality …

Is there a way to use listeners to solve this problem ie to disable the parent, whilst still keeping its children enabled …
