Morning prayer symptoms and conditions

I have been really stressed out about the behavior of my 5 year old son. He is having uncontrollable tantrums, crying spells, aggressive behavior towards me, his dad and his 2 year old brother. He does fine at school according to the teacher. So I thought it was our structure at home. We has a very well kept schedule that we don't change very much even on the weekends. So in the last month it has gotten worse including bed wetting, restlessness, and crying episodes for 20 minutes.
My sister told me about a news piece that she saw about negative side effects of Singulair in children. So here I am on this blog. I have now had an AHA moment. This is the problem. I will be calling the pediatrician TODAY. Now I know what's going on. Thanks to all of you for sharing your experiences. I will post again with an update.
