My DD is extremely clever/gifted (and is neurotypical). It was always obvious to us from very soon after she was born: she was super alert, very quick, needed little sleep, met all milestones unusually early from day 1. She was clearly gifted, but both DP and I were gifted children as well (both also neurotypical), so it was pretty normal to us.
I was very much like @wittyretort, and had a miserable time dumbing myself down and being bored at school until I got to university. DP got dragged around educational psychologists and Mensa and weird gifted kid crammer schools by his parents (ironically, his parents are not neurotypical!) and was socially isolated and very unhappy.
We didn’t want either of those experiences for DD. So far we’ve been lucky that she was in a good state primary with good resources, and quite a few other very bright kids around to compete with. We’ve tried to encourage her and give her a range of opportunities without too much pressure or making a huge deal out of it (no IQ testing or special courses or Ed psychs or cramming). She’s naturally very driven and competitive, so we have always had to work on helping her not become too perfectionist, whilst also not letting her become bored.
DD got an academic scholarship to a (good but not super prestigious or hothousy) independent secondary, that offers a lot of extracurricular and creative opportunities. We explicitly didn’t want her in a super-academic, super-pressured school; but one that is good, but also unpushy, happy and balanced. She’ll get the chance to do the academic subjects she wants, but not with an overload of school work, and we hope she’ll also enjoy and develop other skills that she enjoys and is good at (art, dance, etc).
We try not to make her academic ability a big thing and treat it like it’s normal. It’s bad for a child’s self esteem to always have to think of themselves as “the clever one”, and it doesn’t make for a healthy relationship with others either. Both DP and I struggled with being bullied, internal perfectionism, and fear of failure/procrastination as teenagers, and were pigeonholed by others as “brainboxes” or geeks. I don’t want DD to feel either defined by her ability or hobbled by it.
