Novices don't appreciate nuance that trained experts focus on ... yes, that makes sense. But children do actually have more papillae (taste buds) than adults. As we age, we may gain skill in describing what we sense but we also lose taste buds which give us the raw sensory input to start with.

Also on the plus side, children also lack bias and cultural filters and blindspots, which are hard to avoid in adulthood. Kids notice things adults do not and kids don't hold back from talking about details which adults have dulled themselves to or have been trained to not speak of for reasons of tradition or politeness. (Sometimes those things need to be said and we're all thinking them!)
