As to child-rearing in T rex, wasn't some juvenile material found with Sue?

I don't know about Tyrannosaurs, but didn't Bakker find some evidence of 
parental feeding of infants in ceratosaurs (from the Jurassic of Wyoming)??  
While ceratosaur feeding certainly cannot be applied to tyrannosaurs, maybe it 
can be used as a model.

I assume you would have to compare environments, availability of food, size of 
the infants (compare the size of the ceratosaurs and tyrannosaurs), etc., and 
even then you couldn't be quite sure of parental feeding in tyrannosaurs 
without exact proof (bite marks on bones, etc.).
