I read your first post in this thread. This is what I feel.
If the school your child goes to is a completely regular school, they are not going to make individual reservations, unless the child has a physical difficulty, like poor vision for instance, they may accomodate by giving him the first benches.This rotation of places is there in many schools , even in my sons school.
This is what I feel - If your child is studying in a regular school, its not fair to expect them to cater to individual childs needs, Lets face it--- Almost all mothers would like their child to sit in the first few benches as some amount of concentration gap is found in all children. What would the teacher do if many parents come with this request of putting their kids in front benches. So if there is a rule in the school , we need to follow it and not ask for reservations. Since the teacher said its only for a day, I'm sure the child is not going to loose anything much. This imo is not a big issue at all, and as you have also mentioned in your post, they are accomodating him very well.
And let me tell you a fact------ Most mothers work very hard for improving their child. If you see a seemingly bright child in class --- credits to the mother!!!!!!!!!!!!! I know this - coz when I was in school upto class V, I always used to stand among the first 3 ranks in class. This was because my mom was carefully monitoring my studies. Once she started her own business, she became very busy to check on me and my grades slipped... So I know,, Its 90% the effort the parents take that will make the child shine, the school will not and cannot do that completely.. Only 1 or 2 kids who are extremely bright on their own can make it with just the schools efforts, the rest of the kids need a lot of supervision from their parents. I have seen how parents slog with their children for competetions, scholarships etc.. So dont worry,,, you are not among the few ,,, many mothers work as hard as you......
