Hi, yes, probiotics help and a multi-complex vitamin too. I also cut out gluten too, which causes inflammation in the body, the brain, digestive system.

my daughter is 8yrs old. she will be 9 next month

How old is your son?

it depends on what the specific challenges are. things like short on patience and temperament can be mended by nutrition, things like hyperactivity and attention span can be mended with omega3 and fish oil sometimes.. but again the answer would have to be YES but depends on the characteristics of the behaviours that lead to the incidents that you are hoping to see improved.
