This is very, very wise advice. Spaghetti clearly outlines what was a goal of our parenting- a sensitive, flexible path that adjusts and changes continually with the growth and needs of their kid. Whether IQ scores inform that or not is up to you and your circumstances, but scores shouldn’t be cause for a major shift or detour.

Your kid is still the same kid, no matter what the scores reveal, and you should keep on keeping on, as it sounds like you’re in a good place, doing a good job.
