Who is Kachu? Her first doll with hair.
Why Kachu? Because she named it so. Her first choice was a boy name. When I pointed out the doll was a girl, her next pick was the gender-neutral, one-of-a-kind name, Kachu.
What does Kachu mean? I'll have to ask her. I'm sure she can explain. She has an explanation for everything.
Yesterday, I found Kachu in her cubby at school, minus the clothes. So I asked her about it, and she knew exactly where to find everything. Kachu's shirt was hanging on Summy's coathook, and Kachu's pants were in the winter gear shelf.
Kachu gets to ride on the front bar of Summy's trike everyday. Summy even gave her a shampoo the other day.
