Thank you for the great feedback! To answer your question, I would go through all these 9 videos when I'm done with them in just a few weeks. Then, decide which one sounds like your child the most! You can also see a list of all these characteristics on my Instagram account (@gospelforenneagram) or Facebook (/gospelforenneagram). You can also download my free Self-Typing guide for adults in the video's description. You can learn a lot about each type from that guide as well.
Man, i thought i was a 9, but relate to this too. It took me a loooong time to figure out that I'm a 9 but maybe I'm a 6...i have to look into it more and compare.
