I don't know what to do... We had our second son after a long process of trying,1 year and 2 M/C later we have our rainbow baby

. I was able to take almost the entire summer off so we can have some fun but, DS1 who is now 4 has turned into a monster

. He is rude, nasty and at times just mean. He targets me primarily, today at nap he punched me in the eye for no reason. Last night while I was dealing with colicky DS2, DS1 colored all over his walls with crayon. We have tried rewarding his good behavior, keeping him busy, sticker charts, special time with me, etc. I am not sure what to do. His behavior is causing DP and I to fight because he doesn't do these things to her. We have tried time outs - but he was destroying things, taking things away - he states that he doesn't care, Time in which is usually walking with a parent - but he tries to hit/kick/bite me, etc. It is really sad, I am actually in tears writing this, I don't know what to do. I am considering therapy to help him through the transition but I am not sure if that would be helpful. I am at the end of my rope; please help!
