I think I probably am a lazy parent - it's all so knackering. But philosophically, too, I just think my job is to set my kids up to make choices and achieve balance. I'm also faintly unimpressed by high performing toddlers - perhaps because I started school way way ahead of the other kids (reading before 3) but it turned out that was my peak and I have been resolutely ordinary ever since.
On music, in my teens I was friendly with Hephzibah Menuhin, sister of Yehudi and a concert pianist in her own right. She used to have me round to stay and helped me with my piano practice, and sometimes I'd turn the pages for her when she made records at Abbey Road. Her parents had invested everything in getting their three kids to be musical. They started at 18 months old and by the age of 3 were having to practise 8 hours a day.
It clearly worked with Yehudi. But Hephzibah told me it had killed off all her joy in music. She hated playing the piano, just did it to earn money to fund her real enthusiasms (feminism and human rights). So what the hell was the point of that? Just to make her parents proud?
If you are hothousing you are making choices about your child's future interests and career, because there isn't time to do everything. So there is a high chance you will get those choices wrong. Far better, I think, to raise a well balanced child who can make their own choices. They won't be a child prodigy. But they may be a happier adult.
