The word you're looking for is "No"

For the first time in recorded history, toy manufacturers are marketing their products directly to children. During the holiday season! Some parents have written to toy makers, asking them to stop advertising during "Dora the Explorer" in these troubling economic times.

Fark perfectly captures my sentiment: "Unable to say no to their precious snowflakes, parents send letters to toy companies asking them to stop advertising." Good gravy.
