Let tell you real life scenario. I am not telling what I am doing is best approach but this might be most approachable for most of parents like me.
As per my experience as father of two young kids , if parents helps kids understanding some of cartoons it helps them.
My kids at age of 4 can identify 15 dinosaurs due to "dinosaur train" and he knows so much about wild animals and different environments around world due to "Wild kratts" and "Octonauts".
He is certainly at level where he can talk about this things with adults and have meaningful conversation for hours. All of these can't be possible without these cartoons. Specially most of things where not knows to me. How can I teach him all these things with books ? He is so much interested in dinosaurs he wants to be "paleontologist", terms which was unknown to me 3 years ago.
He has so much positive impact, he takes care of his environment and make sure no animal get harm.
His vocabulary is 2 years ahead of his age due to it. He started coming with me on trails and small hikes to view animals and ready to sweat out for it.
We might not had opportunity to view all these things and in our time there was different requirement for kids. In today's competitive world gaining knowledge more faster and earlier is kind of norm. We keep try to train our kids way we got train. That is not progressive.
For political party to speak against individual series is pure BS. They can be more positive influence on kids by implementing better education reforms and pushing fro more progressive curricular. This is nothing but to please narrow minded , so called right wing pseudo nationalist people for short term gain. We know that group of people are loud so voice of sane people will get buried.
