That is completely untrue, and is probably an indicator of lack of listening and understanding of what the kid is communicating of which most is non-verbal. The need to hit a kid is 100% a failing of the adult.

How do you discipline your 3 year old?
There is no "listening" to a screaming tantrum and wilful disobedience.
All other attempts at communication have failed, the child is frustrated out of his wits. They are constantly communicating something, mostly love. 3 year olds do not need discipline. Kids I raised never had a screaming tantrum, they got their point across without it.
