My daughter is 5 years old and has been on Singular for almost a year. My daughter luckily has not had major mood swings but I did notice that she was starting to have nightmares at night. It was to the point where she would wake up crying and refusing to go back to sleep or get back in her bed. Everynight she started to have nightmares and not want to go to sleep. I took my daughter in to see the doctor about an ear ache and mentioned that she was having nightmares at night and thought it might be the Singular. My doctor said that she had several pediatric patiences who were experiencing the same problems. She recommended that I switch it and give it to her in the morning. I am now afraid to give it to her at all with all the problems I am hearing about now. It's a no win situation because she needs it to control her asthma but I don't want my child to risk having suicidal thoughts.
See if there's a safe alternative to Singulair if your child requires it. That would be my two cents. You can see my other posts under matthewct1. Best of luck
