Yuuki is always following after his sisters and wants to do same things.
So when she started to clean up the bath he did it too. So she teaches him how to do it.
By the way yuuki’s job is ……
Actually he plays with toothbrush but he can do good job.
My daughters Akari and Hikari also did it with me when they were small, but they are good helper now.
What do you do next ,Yuuki ?
