Someone I know who is an educationalist (not a teacher) has suggested that my son (age 7) is hyperactive or similar. His school has never suggested this and I am not sure that we are not talking about normal boyish behaviour or something greater than this. He is a high achiever at school but his concentration can be very poor. He has suggested cutting out squash etc. I am happy to do this sort of thing without a professional diagnosis etc but I cannot see how this small thing will do it. Is there somewhere I can look to see the type of thing I should be doing? My son is not a big junk eater though he has fruit ice lollies in evening (additive free) but I suspect if I am going to do this I ought to make sufficient changes to make a difference. Thanks very much.
