I can see why this would concern you - but I don't think the problem here is intelligence - your son is obviously very bright - but like many children, he has difficulty focusing on subjects that don't hold his interest.I do still think that he may be highly sensitive. But I think if he is experiencing academic difficulty to the point where he may have to repeat 2nd grade, then there may be another potential problem going on. I can't say for sure without meeting your son in person, and he would need to have an in-person evaluation to determine exactly what is going on and why he seems to be suffering from attention difficulties and problems focusing in certain subjects, but it is also possible that he is suffering from ADD
. It's an over-diagnosed disorder, in my opinion, but it's something you should be aware of. Children with ADD often have no problem achieving high marks in subjects they are interested in, while they suffer in the subjects that do not hold their interest because they aren't able to focus. And it's not so unusual that he does well in spelling, because many children with attention problems actually have excellent memories. But it's very difficult to say exactly what is causing this problem, so I would recommend that you think about bringing him to have an evaluation by a child psychologist, just for your own peace of mind. If there is an underlying problem, then certain treatments can help (therapy, medication, although there are many other possibilities that do not need to involve medication as well.) You might also want to review this information for your own knowledge - but beware of doing too much reading on the internet without consulting someone in person:
Getting him in for an evaluation during the summer break may help to uncover what's going on with him before the next school year starts, so that would be my advice at this point. I hope this helps, but please let me know if you have any more questions or want to discuss this further.
