Well after reading these posts...I am very sad that I didn't read...

I am replying to my first post here yesterday....So today I didnt give my 3 yr old son the singulair and do not plan on it ever again! I have to say though...I am very very concerned. I think tonight I truly saw one of the bad behavioral side effects :( He got upset over something so small. Said he didnt love any of us, he didnt want Chinese which is his favorite! He didnt want to do any of the things that we gave him options on that he normally would jump right up to do! This devastated me! I right away thought to myself is this going to get worse before it gets better? He is still complaining of back pain which I know that will take some time. He punched a little boy just before dinner in the neck. He walked out of the neighbors house to go home and usually I have to carry him out. This is seriously scaring me! I'm not sure what to do ? My fiance, his father, doesn't understand and started to yell at him for his behavior. (We dont get much time to talk and when I try to his dad just says he is ok but I know, deep down he isnt) I am the one with him everyday at home taking care of him. I am now being more patient with this behavior when normally I would lose patience and punish him with time outs. Do I continue to do time outs?
Why should I punish him when its not all him ? This is so unfair :( I mean, he is a boy and yes he acts like one. Doesnt share at times, hits sometimes, he is a or was a normal 3 year old boy. His dad will follow my footsteps on this as he see's how I handle things but I'm a little witty on how to handle it now. At this point I am babying my baby! I will tell him when things he does is not right but I'm at the point now that I dont want to send him to preschool! Do I inform the teachers? Can someone give me some words? Its just hard because he is my oldest and is only 3 so not only am I learning to deal with regular behaviors, I now have to understand how to cope and deal with this until its over. Thank you in advance very much for any help and advice!!!!

Also be careful of the Zyrtec. My daughter was on a combination of Singulair, Zyrtec, and Advair and she slowly slid into a depression and committed suicide after being on these medications for three years. At that time there were no reported links to these medications and depression. The Zyrtec doesn't seem to have quite as profound of side effects for people, but it also can cause depression and mood disturbances. Go to the Zyrtec site and read what people are posting about this medication, and all medications that your son may be taking.
