this is from the Baltimore Catechism which is probably what your wife studied.
Q. 632. Where will persons go who -- such as infants -- have not committed actual sin and who, through no fault of theirs, die without baptism?
A. Persons, such as infants, who have not committed actual sin and who, through no fault of theirs, die without baptism, cannot enter heaven; but it is the common belief they will go to some place similar to Limbo, where they will be free from suffering, though deprived of the happiness of heaven.
Note that she either didn't listen past 'cannot enter heaven' or is confused.
Note it says "common belief', not 'infallible Church teaching'.
Note that it says "similar to Limbo", free from suffering, etc.
And note again "common belief." We know that those unbaptized (either water, blood, or desire) cannot normally enter Heaven but we trust to the mercy of God. They 'cannot' enter without baptism normally but we do not know with certainty God's decision; that is why the correct teaching regarding the norm was given but the fate of infants was only noted as a 'common belief'.
There would have been no need for her to read any further. "Cannot enter heaven" is a definitive statement even if there is disagreement on where the unbaptized infant might go. The current catechism says they might indeed gain entry into heaven, but this older catechism does indeed say "cannot". Of course I am not sure what weight the Baltimore Catechism has in comparison to the current catechism. I'm assuming the Baltimore catechism had approval of local Bishops while the current catechism has the approval of the entire church.
