I don't know, this is the realm where only an expert or a native speaker can comment. In Russian we have "жопа" (zhopa) to designate this part of the body, which is the most common vulgar term for that to be used between adults, while "попа" (popa) is the child's variant which is not considered vulgar. Hence "жопа" or other vulgar variants are not used when speaking with children, but "попа" is used instead. However, "попа" is perfectly OK to be used between adults, especially when you don't want to sound too rude. Wishing somebody to "go to ass", you could say "go to popa!" instead of "go to zhopa!"
Besides, the dictionaries are generally limited and may not catch all uses. E.g. "Misch" might have been not only for use with children.
