It sounds as if the father is under the impression that the meds should be taking the place of parenting skills. Pretty indicative of our society's attitude toward meds.
Yes, that scenario was an excellent indicator of the misunderstanding of meds. But then again, good ol' Doc Spock really screwed up views on parenting.
That particular father is dealing with a kid who has kicked holes in every wall in the house, ripped two doors off their hinges, and ripped a bathroom sink out of the wall. The kid clearly does have some serious mental problems, and should probably be institutionalized. A generation or two ago, the sort of "parenting skills" used to deal with a child like this involved beatings and being tied up or locked up. While an argument can be made that in SOME cases, those approaches are warranted, the fact is that eny parent who tries to employ them now will end up losing custody of the kids (who will be put in foster care and given the prescribed cocktail of medications) and quite possibly end up doing prison time. That state of affairs is not the doing of the parents who are faced with how to deal these extremely troubled children.
