I disagree. Abuse is anything that harms the child. Injecting it with harmful bacteria is abuse. There are those (mostly) women that make their kids sick on purpose so that they (the mothers) get attention. That is child abuse. Putting stereo headphones on your child every day and 'cranking cool tunes' is abuse. Telling your child all the time that they are worthless and you never wanted them is abuse. Tormenting a child mentally is abuse.
Of course, we dont know about most things like this (and most are not carried to extremes)...and we cannot always stop them...but it doesnt mean the abuses dont take place.
