I have a 19 month old son that's always been a "daddy's boy". Well, my boyfriend had to go away for a few months. Ever since he's been gone, our son throws horrible temper tantrums constantly, usually over nothing. He will scream so loud, his whole body shakes. I've tried everything from time-out, to ignoring him, putting him in his bed, giving him what he wants, and spanking. Nothing works, it will last up to an hour until he just finally decides to stop. It is totally stressing me out, any suggestions?
