As a parent who went through 2 years of psychological testing & food allergy trial and error its worth the time. My kiddo doesn't have any real food sensitivities except sugar which we keep to a minimum and try for the most organic option when possible. However his impulse control has been slow to develop, so we've given in and tried medication. Its a short term solution in my opinion until his emotions mature enough to keep up with his brain. However I feel like I really tried every alternative out there before resorting to medication. Other parents ask me should I try medication? I tell them take the time and make sure its your only option. My kiddo was in pre-school and having significant issues so we were able to evaluate his issues early before kindergarten.
