A sleepless mother

I woke up this morning at 4 am. It has been this way for the past couple of days. I just wake up thinking of something and can't go back to sleep after that. The only problem is that when I wake up, Pickle doesn't continue to sleep as soundly. He is used to my touch, my smell and will either wake up or start crying in his sleep. No matter how much Z soothes him, he just wants me. This happenend again soon after I woke up this morning but it went on to Pickle throwing himself on the bed over and over again and screaming and showing his anger. I don't know whether I am more sad and upset about him waking up or his expression of anger. I do not want him to get a temper like some people on my side of the family. I HAVE seen anger and tempers ruining your peace of mind in a very intricate and maskable way when you become so used to bearing with someone's temper that you just accept it. Its very scary coz simply, there is no way to deal with anger especially within your family and I have seen it in my Uncle's family and more. This probably is just a toddler tantum but the levels to which it goes scares me off. Instead of going crazy myself (whom am I kidding, that I am, thats ingrained) I just go hug him and reassure him as my first reaction. But the rage he has been exhibiting lately sometimes is very scary. Will my son possibly turn into an angry person? He is otherwise a strong-willed and very happy baby. I must add that he is two days into transitioning from his current classroom into another classroom. The first day was smooth but he was upset the second day. I am attributing his temper to the fact that he is probably insecure with this change. I need to read up on this and also talk to Ma for suggestions. In the meantime, if you are reading this and have anything helpful to offer, please leave me a comment.
