My eldest had a thoroughly miserable 6 months at the Steiner kindergarten which used to be on Balham Park Road, before we couldn't take it any more and pulled him out to go to the local state primary (which had been full at the start of the year)
There were many, many problems while he was there, but the biggest one was that ds has a recognised neurological problem (as in, diagnosed by Great Ormond Street), but his 'teacher' decided that, oh no, that wasn't the case at all as her 'research' (i.e. googling) told her that this particular problem wasn't diagnosed at 5
Instead, she decided that any problems he had were as a result of incomplete reincarnation - his soul wasn't ready to go back into a body, and that he had probably committed crimes in a previous life involving his hands
this was told to me with a completely straight face and when I said I wasn't prepared to carry on the discussion about my son along those lines, I was told that was my prerogative, but I had to accept that while he was in the school, all the teachers would view him as a 'failed incarnation'
Thankfully by this stage the local primary had a reception place, so we took ds out of there as fast as we could and sent him to sanity round the corner
When I told his 'teacher' he was leaving she told me (in front of ds) that we were making a huge mistake and that we'd be back within weeks
we were driving past the site a few years later and ds suddenly said "That's where kindy used to be - I HATED kindy and I HATED xxxx (teacher)"
It really isn't all lovely, child-centred, natural education ... there are some deeply loopy ideas underpinning the whole flaky edifice - and the schools keep very quiet about them ...
