Like most Moms, we like to see what may be ailing our child... and look to alternative sources or nutrition. That is good to keep an open mind and many things can cause something.
Meanwhile, your child is having stomach pains regularly, and is aggressive toward his brother. You do not see too much correlation with his diet per the behavior.
Next, have you looked at their social development? Siblings often fight... but if he is this way with others... have you thought about his over all well being and EMOTIONAL happiness or stresses? This can cause mis-behavior. AND, stress can cause stomach aches too. I know...my husband is the same way since he was a child.
Then, since this has been going on for 1 year... that is a LONG time to just sit idle about it and NOT have an "answer" about it yet, or a CONCRETE solution, or a CONCRETE insight about it.
Now, is this a "nutritional" problem? Or, a "behavioral" problem? These are 2 very different issues.
have you spoken to his school (if he goes to school), and asked if this happens at school? What then? Or why?
Next, have you asked your son why he acts this way? Maybe he is lacking something he is not getting at home... many kids act out when they are frustrated or unhappy or stressed, or misunderstood.
The point is, this is all guess-work right now... for the past year.
I would really look into whether or not he is having possible problems at home or school or what not.
So, there can be MANY reasons why. To only concentrate on the nutritional aspects may be limiting your "solution" to this issue. And, blood-work, if this is a medical problem, CAN reveal many things. It is about ruling out possible causes or not.
All the best,
Susan
