This child is going to kill me.

I nanny for 5-year-old twin boys, one of whom rarely shows remorse and seems to think hurting others is fun. I love both boys, and have been trying for the past year to work through the increasing behavioral challenges with this child. After today, though, I'm thinking about leaving.

It all started because this boy--"Toby"--wanted a special toy that belongs to his brother. He was told no. All morning, this ate at him. He kept bringing it up, shouting and stomping each timr he was denied. Finally, he was getting too upset over it. I usually will hug/sit with/talk it out with the boys when they're getting this way. I went over to Toby, reached out my arms for a hug. He smiled, looked right in my eyes, and then reached out, yanked down my shirt, and bit me on the breast.

Really. He just leaned in, like he was going to hug me, gtabbed my shirt, yanked it down, and bit me, HARD. It was like he was deliberately going for the most sensitive area possible. I have a high pain tolerance, but I screamed. My first instinct wad to hit/push/do whatever I had to to get him off, but I fought it, and I pushed against his shoulders as lightly as possible... and he would not budge. I had to squeeze the sides of his mouth, forcing his mouth open, to get him off of me. Then of course I'm crying/upset, saying "No! We don't treat people that way!" And he laughed. Then he split all the knuckles on one hand by punching me in the mouth, laughing all the while.

It was time to go to school, so I picked him up (kicking and screaming) to take him downstairs. I tried talking to him calmly, I tried letting him sit/calm down, I tried consequences...I finally got him into his shoes, and he promptly started kicking me in the stomach. He saif he wanted to go to school, so I got him down the stairs. When he got into the car, he was mad again, but I finally got him buckled in, and shut his door. His twin, on the other side, was sitting quietly in his own seat, ready to leave. As soon as I closed the door, Toby unbuckled himself and launched himself at his brother, repeatedly punching him in the face before I could pull him off.

I called their grandmother and asked her to meet us at the school, so that I could at least take Toby's twin inside. Toby had calmed down enough for me to drive, and his brother was shaken but otherwise okay. As we drove, Toby started matter-of-factly saying things like, "I hate you. I hope you die. I'm gonna tell Mama you hit me. Then you can never come back. So ha!" Then he would laugh. It was disturbing.

The moment we pulled up next to his grandmother, the smile vanished and was replaced by a pouty lip and puppy-dog eyes. She opened his door and he says "Grammy, I'm having a bad day!" And promptly starts wailing. Totally dry-eyed... It was like a switch flipped. Scary to watch.

Anyway, his grandmother took him for the day and I spoke to his mother about the behavior. I don't know what she plans to do, if anything. I myself am at a loss--I have NEVER seen a child behave this way! When I was speaking to his mother, he was trying to get her attention, and she firmly told him no. He responded by punching her in the stomach and the laughing about it. That was when I bowed out. I could hear her shouting.

This kid clearly has behavioral problems that I didn't sign up for. Is it wrong that I want to leave? I don't know that my mental health can take much more of this. I don't want to get punched/kicked/bitten every day. He's large for 5. It hurts. I don't know that I can continue to keep my composure with him. I have a deep, purple-black bruise where he bit me, and he split my lip. I don't want to keep doing this.
