Violinist64 when you say 'true talent will just shine', I don't agree. That's not my experience in 20 years of teaching piano. It has to be nurtured. There is debate as to whether perfect pitch is genetic or can be taught. What is certain is that if it is not present at the age of around 3 it will never appear later. This, I suppose, is one thing which makes me very much in favour of hothousing. There are some things which you just can't learn later on. I've noticed that elite musicians (and I know a few) always have had at least one musical parent, have started very young and have, intentionally or not been hothoused in music to some extent.
I'm inclined to think that although pitch is perhaps one of the clearest examples of a talent that requires special nurturing early on, there are probably other fields where it is worth doing a bit of extra work with your toddler.
After all we live and die by our brain, these days more than ever. It seems worthwhile to give your kid a boost.
Also I'm not calling parents who don't hothouse 'lazy'. But be careful to consider whether the philosophy whereby we decide to let our children 'find their own path' is born of wanting what is best for them, or is it just making convenient excuses because this form of parenting is so much less labour intensive than 'hothousing'. Same goes for discipline. It's convenient to be a liberal parent, but is it really best for the child in the long run.
Peace everyone. P.S. he sometimes gets an octagonal prism confused with a dodecahedron. Bit of work required but he'll get there by 3.
