DD is 2 (just) and when she gets frustrated she sometimes will try and pinch me or DH, or pull our hair. We obviously say no, don't do that and she'll immediately do it to herself instead. We tell her not to and she stops (quickly) but it's really worrying me. It's not a regular thing but even occasionally it is horrible. I know it isn't the same thing as self-harm done by an adult but I don't want her to equate feeling out of control with hurting herself. After all, she is a toddler and frequently out of control!
Any ideas on how to stop her doing it apart from gently moving her hands away and saying no, don't hurt yourself DD? I want her to know it's serious but I'm reluctant to shout, especially as when she does it she's already in a tizz about something.
