Just a little phrase thwon in the whole discussion
About 子ども. Nagoyankeeさん explained in a thread why always more people tend to write 子ども and not 子供 (which is the same reason Kyle explained).
I can't find the post anymore, but if I well remember he said that the conversion to 子ども from 子供 is rather recent, thus people still write it as 子供. But I might remember it wrong...
