Interesting topic! Reminds me of when I took a Uni class 'health across the lifespan' the majority of the class was learning about psychology and how it shapes people's lives. I came away from that class having learned a lot about parenting- my favourite is Eriksons theory on the stages of life.
0-1 year old Children learn trust vs mistrust
1-3 years old autonomy vs shame and doubt
3-5 years old initiative vs guilt
5-10 years old industry vs inferiority
10-20 years old identity vs confusion
20s and 30s intimacy vs isolation
And the list goes on.....
Even though the list here seems concrete it was explained to us that each stage overflows to the other and doesnt necessarily take place within those ages. The text book I had was a medical one called "Lifespan Developement"
It also had examples of differing ways that people put each concept into practice.

And that's my 'technical' view.

I truly believe for our kids to show us voluntary respect (out of love) not forced respect (out of fear) that is what we need to show them.
Both respect toward them and respect toward others around us.

I have seen families where the children were shown respect, taught they were important individuals, but because the parents didn't show other people (other adutls especially) respect in front of the kids, those then grew up thinking that they were the most important thing in the world and showed little respect for others. Now I know that is an isolated case, but it has stuck with me for most of my life (I grew up with these kids, egh) so I thought I'd share.

To everything there is a balance.
