This is totally normal with some children and people in general. One of my boys is the same. I go a head and make sure everything I do for him is exactly as he wants it. In day-care he will face reality where it won't work for him as easily and that's good. Read, Raising Our Children, Raising Ourselves. It helped me so much.

The fact that you are easy going does not guarantee that your child will be the same. It is often the other way around. It is not your husband's fault either. It is not a fault. it is just how he is. Love him as he is. Don't give him a message that something is wrong. He will face the limitations of it along life.
