I have never had to care for a child. However I can give a few pointers from a child's viewpoint.
1) Never leave a mark from abuse on your child. The child will study it and
think of revenge.
2) Never yell or scream at your child. It indicates that YOU have lack of self
control. Instead use "Command Voice" and a threatening intonation like a TI
does.
3) Never curse your child, someday you will pay for it.
4) After scolding your child, demand that the child explain back to you what was wrong and WHY it was wrong. This will clear up a LOT of misunderstandings.
5) When your child is good, offer praise as positive feedback.
I invite others to comment upon these suggestions....
