A subclass only inherits non-private superclass members. See this for more info on inheritance.

You could try reflection, but if you run into this problem it generally means a) you shouldn't access that private member, or b) your parent class is badly designed for inheritance.

In my opinion, this is actually common. When someone designs a class, they are thinking... "This variable is used for internal calcs, it should be private" or "This variable should be exposed, so I'll make it public, or provide a getter". I don't anyone thinks... "This variable will be used by a subclass, that I'll need next year, so I'll make it protected".
In my opinion, it may be best to go back and refactor the superclass.
