The connection which is breaking day by day. Relation of parents with children.

There are so many important things b/w parents and their children, but two of the most important things are trust and communication.
Trust:
If your trust is broken on your child it could take at least 2 years to regain it, for example if your child see a chocolate in the fridge and ate it, but you saw him while he was eating it, don't be angry at him at the point, just do something to seek his attention, because if you scold him at the point, he would try to steal it again, but this time so careful that he would try his best to not let anyone know. So next time you put a chocolate in the fridge don't change it's place, put on the previous place. He would know that my mom/dad didn't mind so I should ask them.
Communication:
If you don't know what your child wants, what are his favourite things or he's scared while talking to you, this could be dangerous for your relationship, especially the last one.
If you don't trust your own child and think that he has done a thing wrong on time and would do it every time, this thing will be stuck in your child's brain for ever and he wouldn't do that thing right any more. If he's out late at night and you thing he has done anything wrong but he didn't, but you still tell him that you have done this thing, this could feed one thing in your child's mind "if he doesn't trust me, there's no need to make him trust me" and you would be black listed from his convincing list.
