I know we have touched on this before here, but I would like to get opinions on it again. My almost 4 year old has had some behavior issues lately, and we are trying to pinpoint triggers. I know it may be far fetched, but I'm wondering if her diet has a little to do with any of it. She always has constipation issues, so it made me think it could be a possibility. I'm not sure where to start to see though. We have tried eliminating red dye before but we didn't stick with it long enough. Any thoughts for me?
