shameless plug incoming
I’m trying to gather together resources for getting into reading in one thread to help people out, and am just wondering how you’ve found reading children’s material like that? I’ve always struggled with the lack of kanji in children’s books, but I guess they may be the best option available if someone wants native material rather than going the (expensive to boot) graded reader route.
You could even post about it in that thread if you like 
sorry to go off-topic, JarPas, but maybe you’ll find something in that thread helpful?!
