I don't know what to do anymore. When DS gets frustrated, especially out in public, he resorts to pulling my hair, slapping me, and biting my shoulders. For example, we were waiting in the pharmacy line yesterday (it wasn't a long line, just a couple people), and I was holding him and singing to him. He was perfectly happy until I had to switch him to my other hip so I could open my purse. At that point he wanted "down", which is fine. I put him down and held his hand and told him we would be going home right after mommy paid the cashier. He then started knocking the candy off of the shelf, and when I told him he could not do that, he bit my leg. I picked him up and asked him not to do that because it hurt me. He then grabbed my cheek and pinched it so hard I have a huge welt and then bit down on my shoulder. All the while I am trying to swipe my debit card and asking him to please stop because he is hurting me. The teenage cashier looked absolutely horrified. My left shoulder looks awful with huge bruises and bite marks because this has been going on for awhile. My son is usually sweet and affectionate, but if he gets in one of his moods, he is downright violent. We do not hit. I don't believe in any kind of violence whatsoever, so he is not exposed to it. I do not understand why he does this to me. I know that I need to minimize his frustrations. For example, we were waiting in the pharmacy yesterday just before naptime, so I knew he was tired. The problem is, sometimes I can't time things just perfectly. Sometimes he will get frustrated, and I would like to teach him a healthier way of dealing with it rather than hurting mommy. My DH thinks we should start doing time-outs. I really did not want to use time-outs, I had hoped we would not need to. Plus, when this stuff happens in public, especially someplace where DS needs to stick close to me and I can't just set him down, time-outs wouldn't work anyway. Does anyone have any suggestions? Besides the fact that I don't want my son to deal with his frustration through violence, I also do not want to portray myself to him as a victim, and that's what I am feeling like lately. Honestly, if you could see my face and shoulders, you wouldn't believe those marks came from such a small and beautiful child. Please help!!
