Yippee OTG mom!!!
I love it when the little sisters - who are often so sunny and well behaved that that 'couldn't' be that gifted - do get tested and are found to be very similar LOG to their more 'unusual-looking' big brothers!
When I talked about testing for DD with our principal, (who has gifted experience), she said, "it's not like she is doing calculus". I immediately thought no one has given her the opportunity to do calculus and this lady is never going to understand. I just smiled.
This testing gave even more validation that she really needs to go to the gifted school.
