@Speedphoenix Is kodomo a well known demographic used in Japan? I don't know much about it
As for chiisana mori no ookami-chan counting as Kodomo, we don't want to be assigning demographics to series based on what we personally think would be the demographic. Demographic is almost entirely determined and tagged by the publication the series is published in
@Plykiya
From this image I found (see spoiler, though I don't know how accurate it is), it seems Kodomo is more popular than Josei, which is available on MangaDex. That said mangadex.org probably has more traffic on Josei manga than Kodomo.
Things like doraemon or pokemon are pretty much kodomo. Most of children magazines are dead though so, it's practically guessing game whether one is made for children or not.
Also no, Chiisana ookami serialized in comic alive which is shounen
