My DD, 2, is driving me MAD, constantly switching all the lightswitches on and off - they literally make a frazzling noise at times.. What can I do? I´ve tried "NO!" and nothing else, told her it´s naughty, slapped her hand (sorry : (.. everything I think of.. She does it all the time, though more when in a bad mood! PLEASE HELP! This situation is really getting to me!
