My grandson has been in school since 2yr. 2 months and now he is 5yr. 2months old. He always was very active and also had the habit of getting up from his little table and moving around a lot. He also went through the bitting syndrome and he did and still hits his companions. I can't cover up for him and although i know other children are bothering him he shouldn't hit them back. He's in his last year of kinder .......and I would really like to know if he has ADHD. He's taking DHA, primrose oil and his daily vitamins, he has a great diet....loads of veggies, beef and chicken.......fresh fruit and fruit juice.....no milk or white bread...and forget candy and chocolate......can you help me? Or is it a conduct problem? He lives with my daughter whom is a single mother.
