Ledge, I have a little one who has taken to using her clay to shape phallic objects. I find these drying EVERYWHERE. I was horrified, but a friend who has come to a unity with her system told me, "Don't make her stop and DO NOT throw them away or remove them. She is working through something and she wants you to know."

My instinct would be to tell you that he's trying to tell you something, and when you wash it off the wall, the message is that you don't want to "hear" it. If at all possible. . .find a wall that can be his and his alone - the back wall of a closet for instance? - and let him go to town. He's trying to tell you something, and it may only become clear once he's drawn several pictures for you.
