@pragmaticmom - Wow - one way to end a conversation is to say ’ do the genetic superior parents have an answer? I will try to answer your question without aspiring to the ‘genetic superior’ label.

From this chart it is clear that there are functioning people in all kinds of occupations with a very wide range of IQ scores. I wish they had put homemaker or Mom in the listing.
I didn’t think the original question was about ‘normal’ kids unless you are saying that all of the respondents are seeing above normal in what are really normal kids. A Garrison Keillor/Lake Wobegon kind of misconception.
My anecdotal response is that I think that there are discernible differences between normal kids as well as observable differences between normal and above normal intelligence kids. In the same way that you can see differences in a person’s athletic ability along a spectrum of ability and effort. You ask if the difference in their performances is sufficient to justify the attention we’re giving it? I believe that every kid deserves an individualized response from their parents that takes into account their unique circumstances. I think we all want our kids to be happy, content, safe and fulfilled in their lives. We hope that our efforts on their behalf aid in that outcome.

The above article lists ways that more ‘intelligent’ people have an advantage in our current economic./social. environment. I hypothesize that you can find research that says height, athletic ability, normal weight or beauty confer benefits.
So - do I pay attention to my children and their ‘distinctiveness’? Yes, happily.
Do I recognize that there are ‘normal/non-distinctive’ aspects to them? Yes, happily.
Do I think their differences justify the attention I/we are giving them? Yes, happily.
Are you trying to ascertain "how did your kid become so darn smart’ or some other question?
