You stare as your daughter lines up her toys, first by color and then by size. You’ve long ago ignored the well-intentioned friends and family who told you her behaviors were “typical.” There was nothing typical about it. You spend most of your morning sitting where she wants you to sit, following her very specific demands. Demands that if not followed to the letter, will result in a catastrophic meltdown that can go on for hours. You are pretty sure your child is showing early signs of OCD. That is not rocket science to you. But what you really want to know is how to deal with OCD – especially in a child this young.
