Each of the 40 assets remain the same for each developmental stage while the application of assets change based on the age of the child. They're worth a look.
I took a particular interest as I have a son in each of these developmental stages. Suffice it to say, I have some reading to do.
When I first saw this chart, I thought, "Man, I gotta get my kids 31 of these assets."
But then, when I saw this chart I thought, "Holy, crap. We're doing something really wrong."
Figure it out in the comments, will ya?
[1] I have no idea if this is even a credible organization. I learned about this today at a meeting I attended and it was the one thing that didn't make me want to stab myself in the eye with a pencil.
