my sons do not have adhd but i am very interested in naturopathy. while they are very active, they do not have adhd and have very good concentration levels.
i give water, fruits, yogurts, cheese and oatcakes or french toast throughout the day.
they can have one glass of fruit juice when we are eating out (fresh if poss, organic otherwise)
otherwise it is always water or "special" tea (camomille tea + a couple of fresh mint leaves)
i dont buy cakes or biscuits. For a day out i always take fruits/yogurts with me (yeo valley are the ones with less sugar). i also takes sticks of cheese and carots. i also avoid the fruit purees in pouches. they also like oatcakes and frenvh toast. they occasionally have a square of good quality chocolate.
for pudding it is fruit or yogurts.
if another mum offer them with biscuits thats fine, same for cakes and sweets at parties etc... but i always try to have more fruits than necessary so they can share with their friends (and nicely ask the mum to hide the biscuits).
we dont have a TV so they dont watch cbeebies or other things and i think it forces them to find games to occupy their imaginations and in turn improve their concentration levls. Again, if we are at my or DP's parents thy can watch some tv, same if at someone else.
i maybe sound rather strict, but i have two very happy, smiley boys and our house his full of laughter and fun.
good luck with making changes
