Toddlers often bang their heads against walls, doors, or furniture, horrifying their parents in the process. In a way, that’s the point: While the first few times are accidental, the behavior quickly evolves into an attention-getting tactic. You have two strategies for dealing with head banging: Either put padding on all the walls of your house and ignore it, or just ignore it. I recommend the latter. After two or three episodes, Jimmy will realize that head banging hurts and isn’t much fun. And when it provokes no reaction, he’ll find it even less enticing. If, on the other hand, you try to dissuade him, he’ll bang his head even more.
