Greetings dear @svm038 I went back to my days as a mother of small children, hyperactive and they were 5 years apart from each other, there were three.
Just by changing the diet. Only corn flour, gluten free, dairy free and white sugar. Her restlessness improved remarkably, today we repeat it with my granddaughter, ketogenic diet indicated by her pediatrician and she sleeps peacefully. The sugar in food alters sleep and character. Happy and long life.
