I remembered when my DS8 just entered kindergarten for few weeks. I asked him, "Do you know any kids is not reading yet?" He answered, "How is that possible? Every kid in my class is five or six. Of course everyone knows how to read." At that time he was reading 3rd/4th grade level and he thought everyone should be just like that. Months later, he found out he was more capable than others in some area. I gave him lots of examples that his classmates can do something better than him. Some can write letters like printing, some can swim, some can ride a bike, some can draw pictures with more details. I told him every kid is learning different things in different pace. Even his little sister has different strength and weakness than him. I have never use the word "gifted" when talking to him until one day he caught me was reading a book about gifted children. He asked me, "What is gifted children? Am I?" I told him, "Maybe, I know you are very good in some area. Let's find out when you are older." Now my son is 2nd grade, he is still the top student in the class. But he won't think he is better than other children because he knew his own weakness too.
