Hi Sabina,
If you are just looking for experiences, here is mine: after DD9 was tested last year, our tester told me that it was not uncommon for siblings to be in the same IQ range (but with different strengths). I looked into this myself, and found some sources that suggested the same thing - without LDs, siblings are often VERY close in IQ (

Even though I'd known that it was possible, I still found it freakish that they were THAT similar.
