ild say none of them, although smoking would be the closest.
i think classing things like that as abuse marginalises real abuse.
for me real abuse would include
-hitting a child
-yelling at a child
-using fear and indimidaion to control a child
-anything that makes the child feel unsafe
-taking away/controlling/manipulating basic human function ie. not letting them go the toilet or eat meal or not drink water
-physically punishing/controlling them
personally some of the things/punishments I experienced
-loss of meals
-limitiaton of water
-limitation of going to the toilet
-'eye for eye' punishment ie. kicked my sister = acting like an animal = being tied up on leash and forced to eat of out dog bowl. getting out of bed after bed time = walking laps of the room until I got disy and spewd. getting holes in the pants = crawling up and down the slate hallway on bare knees until they bleed. kickign my doona of at night = sleeping in a dressing gown that was sewn up and then tied to the bed.
I could write for hrs, but yeh I think there is a difference between undesirable parenting and abuse.
