DD has always been a difficult kid. More than normal tantrums, defiance, etc. We've worked with the pediatrician, and saw a counselor who recommended 1-2-3 Magic, which worked for a total of 3 weeks before she just didn't give a crap about time outs. By week 4, I never started counting without having to get all the way to 3 and then drag a violent child to her room. I just didn't work for us. I need to go back to the drawing board and find a new approach, but in the mean time I could use some advice on impressing the severity of certain actions on her. For example- we were hanging out with 4 month old DD2. DD2 was in her seat with an activity tray. I was on the couch, punching in my WW points (literally a 30 second task) and DD1 puts both of her hands on DD2's hand on the tray and puts all of her weight on it. It wasn't like other times when she would do something like poke DD2's tummy to see what would happen. It was malicious and calculated to hurt her as much as possible. I told her to go straight to her room, and am about to go talk to her. The problem is, if I tell her she could make DD2 have a broken hand and need a cast and go to the hospital, DD1 will think that's cool. She doesn't understand that those are very bad things. Casts are cool to kids. She just doesn't get it. I feel like when she does get it, she doesn't care. I'm so frustrated. I feel like every time I turn around for a second, DD2 starts screaming. I look up and DD1 is right there. I watch like a hawk, but I have to blink! She is so quick! I never leave them in a room alone. I'm a mess. Help me.
