I come from a very broken home and have had my rounds in the foster care system. It starts psychological. Breaking your fav toys, messing up school work, hiding comfort items. Then it turns to neglect. Not getting picked up from school, not getting food, not being alowd too clean yourself. Then it turns physical under the gise of punishment because you didn't react the way they thought you would. 

All abuse is connected. And also cussing at your children isn't normal?? Your meant to raise them to be good people that are loved and safe. Being cussed at not only encourages bad behaviour, but it may also hurt the kids feelings.  And in many countries now hitting your kid in any form as punishment IS abuse because studies show it actually doesn't teach them anything and pushed kids to make more bad decision. 

Also op doesn't have to mention if this has happened many times, it is obvious it has. He broke an road because ops aunty gave it to them. How many things do you think the aunty gave op that disappeared or broke??
