In Flintstones, Pebbles is occasionally seen in a white fuzzy diaper. Most of the time, however, she's seen in this black garment worn by Amy. It's hard to tell if this is a different colored diaper or a diaper cover. Poor Amy is afraid to use this garment as it might not be absorbent.

And just because I talked about Flintstones doesn't mean I'll draw humans, so don't request me to Draw Humans.
