He is three, and has developed a thing for washing. He loves to clean. He keeps having to wash his hands and his face, he says it is dirty. It is not. He will get up from bed after the ligths are off, run to the bathroom and wash his face, again. If left unsupervised he can empty all the liquid soap in the sink, fill up with wather, and immerse his hands and arms, take a flannel and wash his face, arms, hands. Etc.
Should I worry?
