I have a 22 month old who doesn’t react well to Kids' Panadol (he gets restless and angry, different to the symptoms of being unwell). I suspect like my 4.5 yr old son he may be sensitive to some of the added ingredients. My older son reacts to additives, glutamates and a build up of sals, he gets defiant, negative, angry and moody. Thank you for the work you do! It has been a life changer for my older son and our family! - Sarah :)
