I found a solution for this problem in another thread I posted. For anyone who comes across something similar, Alex Harui pointed me to the answer on his blog about modules: http://blogs.adobe.com/aharui
My problem was certain objects were being instantiated by one child app, and then the other child apps wouldn't have access to that object. The solution is to create those objects that the apps will share in the parent application. What confused me is that some of the built-in components/object behave this way, in that the first app to need the object will create it for all of the other apps (parent, siblings, and children) to use. In my case, when a child instantiated said object, the other children didn't have access to use it.
