During early childhood years I believe fear and respect tend to be one and the same for most children. Essentially there is "the threat" or (fear) of serious repercussions for disobeying that keeps them in line.
Generally speaking their love comes with maturity and understanding the motives, sacrifices, and efforts their parents made to encourage them to become productive self-reliant citizens.
Long ago I once watched an episode of "Super Nanny" where a mother took away a 5 year old boy's toy after he kept beating it against the table even though she asked him to stop several times.
The boy then slapped her and spit in her face! (She cried)
Lets just say if I had ever done that to my mother I would not be sitting here answering this question today!
I grew up in a era where the goal of most parents was not to be their children's best friend. They wanted to prepare them for adulthood.
Naturally there were vacations, playtime, and other various fun outings but (you always knew) as a child that you and your parents were not "equal". It was not a "democracy".
There was a definite "chain of command" within the household.
