Even though your kids are beautifully bonded, it doesn't mean your eldest child isn't having a few difficulties with the adjustments in his life. He's not the baby anymore, he's starting school, his father in a new job, those are big things.

If you're wondering about food allergies, it's a good idea to keep a diary of what he eats and when the moods happen. I discovered a dairy allergy like that, and it was easy to fix, and we saw improvement within 2 weeks! If you're concerned about ADD or ADHD it's an idea to put him on some fish oil, that can help with the brain connection stuff.

It's so frustrating when kids go off the deep end isn't it! I can really sympathise with you.
