I agree it is the parents responsibility. Over the 1998 holidays I had several flights where children were in first class.
The behavior ranged from very polite, well behaved and QUIET, to the extreme opposite(which we all can describe).
In all cases it was the parents(or adults) involvement that influenced the children.
How can we get behavior info to the parents...
In all cases the flights were on Delta and the FA's did not do anything to the "misbehavin':
