O well I had the same thing happen to my son-at 2. For one thing kids dont do anything that doesnt benefit them, or that doestn get them something. So either from sheer annoiance he must be getting what he wants, at least sometimes, OR at the very least he is getting attention, even if its troubled attention. With your husbands job, and you are clearly busy with baby etc he may be feeling like he has to scream to be seen in the family. I recomend trying to make a 'you and him' time or a 'daddy and him time' even if it is just a story time for him before bed, just him. It takes only 15 minutes and really worked well for our son. Also this age there brains are not at a point of understanding clearly their impulses. My son went to day care, and though he could talk he picked up screaming at class, like other kids. So we just sat him on our laps and until he would 'say nicely' what he wanted, we wouldnt get it for him, wouldnt yell at him, threaten him, wouldnt react, I mean we would tell him "you say juice please or your not getting any, no loud, say it quiet and nice' then we would look away no matter the tantrum. It takes time and CONSISTANCY for them to really know you are serious and no matter what you cant give in to the screams, even in public, immediately remove him to the bathroom say and just tell him again, and that you are not leaving the bathroom until he stops screaming, etc. This is hard and embarrasing as well I KNOW! but like I said somehow at the root of all kid problems solved is us parents being consisttant, them getting enough 'me' time and not reacting and giving in to what the bad behavior does, and rewarding the good, SO we will praise the heck out of our son when he asks nice/ We also had the same issue with hitting at school, and its took almost a month for him to realize he liked the benefits of not hitting over the attention and trouble from hitting, BUT WE had to stay consistant! Its hard, stick it out and I strongly recomend prayer too!!! Take time out for you somehow so you are not drained to the core, after reading your description you sound like you may want to scream like him!! LOL!! GOD BLESS!~~
