child
On-Yomi: シ、ス、ツ — Kun-Yomi: こ、-こ、ね
Koohii stories:
1) [lbphenom] 12-1-2008(43): A child who is ten will still ask for his ma (top looks a bit like katakana ma).
2) [Danieru] 28-1-2008(30): A pictograph of a child, with arms outstretched for mother (or perhaps because she is chasing a rat?). Note that this kanji occupies the first space on the Zodiac circle, and is the sign for the rat (such as 2008!).
3) [Po0py] 15-12-2008(21): A ten year old child with a baseball cap.
4) [Jeromin] 21-12-2008(9): A child, from one to ten, before becoming a teen.
5) [NyahK] 6-6-2010(6): I'd imagine most people knew this long before starting RTK. When they were still a child of kanji, perhaps?
