If he's just exploring his interests and his parents are facilitating then that's not hothousing to me. In my experience parents in this group tend not to blabber on about how amazing they/their DC are.
Whereas seeing a child likes maths, is good at maths and then piling on more and more and more and rushing to get DC to sit qualifications at young ages would be absolutely hot housing. The parents in this group seem to want everyone under the sun to know that their children are so much better because of all their hard work as parents.
I saw the same in music when I was a child. One of my peers was a excellent musician and substantially more advanced than their peers, but they were allowed to learn, play, compose and enjoy their talents in a way that was very much self-driven with appropriate support. They were never pushed to be front desk or section leader or soloist, and would often be very happy playing in the middle of the section and supporting leading sectionals. You'd never hear their parents making a huge song and dance about what great parents they were for producing such an outstanding musician.
I also saw a lot of other able and talented musicians pushed into doing more and more ensembles, more grades, more theory exams, need to have a solo, need to enter this competition or that one, and it was a hot house sort of environment. A lot of those parents seemed to think it really mattered that their child was better than others, that Jimmy did his grade 8 at whatever age, that Tabitha is already doing music lessons at the regional conservatoire. They were great musicians but it wasn't a healthy culture from their parents at all.
