A.P.
I had exactly the same problem with my son when he was two. I happened to be working at the time also. I also, out of frustration, tried hitting him back. He’d also hit me back and get even madder than he was before. Time out didn’t work very well for it. I started gently taking the arm he had used to hit me with and, while holding him on my lap (because he’d squirm and kick) I’d hold his arm with the intent of sitting there for a minute and explaining why we don’t hit others. Usually, I would end up holding both arms, and his legs in between my knees after he tried to hit me with the other hand and kick with both feet. Then, because I was unwilling to yell, I waited for him to stop screaming. The first several times he’d scream and cry for a half hour, and I was upset, thinking I shouldn’t continue to hold him there. My mom reassured me that it would eventually work and that if I quit after he cried too long that it would reinforce his belief that if he just cried and screamed enough he’d get his way. Actually, the first few times he cried until he fell asleep, not giving me a chance to explain anything (these times were when he missed his nap time and was really tired anyway). I’d wake him up after a few minutes, and he’d be calmer. I’d ask if he was ready to talk to me, and then explain why hitting isn’t nice, etc. After a couple of months he was still hitting, but less often, and he would only cry for a couple of minutes before he was ready to talk to me about hitting. Before he could resume life as he knew it, he was always required to apologize to whomever he had hit. He stopped hitting me, and I didn’t get any complaints from daycare. As a three yr. old (almost 4), he’s very nice to his friends when they come over. He has a couple who hit him on a regular basis (I try to referee) and he never hits back. We taught him to give them hugs when they hit, to restore good feelings. It’s worked pretty well so far.
Other things we’ve done since have been to get him a “baby,” in the form of a doll that he could take care of. He learned to treat her gently because I treated the doll as if it were a real baby, and would pick it up and comfort it when he’d throw her, and then not let him have her back unless he was going to be nice. I’d even supervise for a while like you would if he were holding a real baby. He now does beautifully with babies and is looking forward to a little brother.
