You could mark your association property with fetch="subselect" - this also makes sure you don't run into problems with a huge cartesian product at the cost of making two queries for each select.
Using the batch-size hint in your mapping for the child collection is probably the best/easiest way to deal with this. For further discussion, see my answer to this similar question.
