My six year old daughter has been on Singulair since she was one. She has bad stomach pains, headaches, mood swings, not being able to do school work and anger. I had thought about taking her to see a therapist. I didn't know what to do about her anger and mood swings. After reading everyone else's post, I feel like that it really could be the Singulair. I have taken her off of Singulair. I will not put her back on it. I pray that she will feel better soon.
