>>3142422I've seen two. One had an elongated scene of a kid getting scrubbed by his mum with two seconds of frontal. Another had a kid grabbing and groping a bare breast. And then there was that show that got cancelled about the princess who fell in love with a 10 year old. There were scenes of them bathing together and sleeping in the same bed iirc.
And you don't need to go further than the first Dragon Ball for Japanese casual child nudity. And don't get me started on every French kids media ever like Le Petite Spirou and Kirikou and the Sorceress.
