To me it sounds like your daughter is doing very well.
You should read the “applying sideways” blog on the MIT admissions web site. The point, as I understand it, is that each student should do what is right for them, and do it very well. What was right for you or me, what is right for your daughter, and what is right for each of my two daughters, may be entirely different. However, if we each do what is right for us, it improves the chances that we will get into very good universities that are a good fit for each of us. We have used this approach, and it has worked well for us.
The other thing that you might want to keep in mind is that the famous universities (on the Harvard, MIT, Stanford level) are each a good fit for some very strong students, but they are not a good fit for all very strong students. After graduating from MIT or Stanford (or both) recent graduates will find themselves working alongside very good coworkers who are from a very wide range of universities, and in most cases and for most jobs no one will care where you got your degree(s).
Also, as parents to a large extent we need to have faith that our kids can handle themselves.
Which might be a long winded way to say that I think that your daughter is already doing very well.
