This patient support community is for discussions relating to the challenges of parenting toddlers (age 1-5), including physical, speech, sensory, cognitive and emotional development, choosing a daycare/nanny, games & activities, and toilet training.
Since you can't monitor what he watches in his room, I would suggest removing that television. If you can't bear to do that, then unhook it from the cable or whatever, get a VCR and get a bunch of VHS tapes (they're cheap, especially secondhand!) and let him watch the tapes. That way you have control over what he sees and you can keep it age appropriate.
The best way to stop a cycle of abuse is to get professional help because someone can tailor a plan to your specific needs. The military has family welfare resources, check your local base or ask at your MTF. They can help you both learn to deal better with frustration and how to communicate better. Perhaps too they can direct you to local resources for activities you and your son can do together, or the three of you together where he is the center of attention.
Meanwhile, although his tantrums seem extreme and most kids his age wouldn't say or do those exact things, it sounds more like a discipline problem and probably exposure to the wrong TV shows rather than something "wrong" with him. He is jealous and he doesn't know how to cope with it, and it sounds like you don't either. When he acts out, you need to step back, take a deep breath and count to 10 or something before you react. Really, it can work! Hitting him isn't going to help but I think you know that, it's just a product of your frustration. Not reacting to him on impulse is key, and by taking a moment for yourself you can collect your temper and react more calmly. You're in a tough situation- more stressful than most of us would be able to bear on our own. You need a break and some guidance, more I think than we can offer you here.
Take a moment before reacting (like the previous post suggested). Can you include your son in some of the aspects of raising a baby, like helping to feed or playing a game together? Tell him what a big help he is when he does this?
Good Luck!
It's VERY common for a child who has recently become a sibling and had ALL the attention for SO long without anyone else interferring to act out when that is taken away. I understand that your daughter may be more demanding in terms of needs but your son's needs are just as important. Please don't give up on that and don't shrug it off.
I suggest some firm discipline and total consistancy (I know it's hard ecspecially if you are a single parent but it is utmost necessary).
I would also suggest one on one time with your son without the babe if at all possible. He will not understand that she needs more attention at his age. Children at 3 think in concrete terms. all he knows is that he gets less attention then he did before the baby came and bingo resentment.
He needs one on one mommy time REGULARLY. Each child does. Its not fair to him to expect him to understand what's going on and it's not fair to him to lose out because the baby is around. Plan something consistantly, an outing to the park once a week, a move afternoon while baby naps. Seriously it will help I bet. And include him whenever possible like miscd said. if you can't be one on one.
Firm Discipline, one on one time and 110% consistancy. When your'e tired and angry and upset none of that can come through as a break down if you get what I mean. He has to know you mean business and he obviously doesn't if the ways you are disciplining now aren't working. I wish you the best of luck.
