Thank you all for your comments.
I know my child is not stupid. He is very advanced in many ways than alot of children his age.
He just dosen't seem to pay attention to a few things and can be a handful to deal with.
For example he knows all numbers and shapes and is very interested but when it comes to colours and letters he just refuses to show an interest.

Well its more of a disorder than a dissability, but my husband reacts as if it is a dissability.
BTW thank you all for your comments.
Hopefully he will grow out of it as he gets older.

Our 4 yr old son has just been diagnosed with ADHD (Attention deficit hyperactivity disorder). I have suspected it myself for a few years that he may have had it but ever since he started school it has become more obvious, i.e not paying attention in class, no interest in learning etc. Ever since we found out, my husband is finding it difficult to accept. He is always calling our son stupid and beating him. I am really upset by this. He is also very grumpy with me ever since and is blaming me for it. He says that he is ashamed of me and my son and that there is no stupid people in his family. He also says that in his country (Nigeria) that is a disgrace to have a child with a dissability.
He's also threatening to have a child with another woman since I didn't give him a bright child.
He is a very bright and clever child but in alot of other ways.
Is it such a bad thing in Nigerian culture to have an issue such as this?
