I sense mockery in your email, and it does not conform to the PSF code of conduct. Please read the CoC before posting in this mailing list. The link is available at the bottom of every python mailing list email. https://www.python.org/psf/codeofconduct/ I don't find teaching children is a laughing matter, neither is the idea of children learning to code. In Canada, we have initiatives like Girls Learning Code and Kids Learning Code. I mentored in a couple of those events and the students are girls aged 8-14. They surprised me with their abilities to learn. I would suggest looking for such mentoring opportunities in your area to gain appreciation with this regard. Thanks.
