I went to a playgroup the other day and saw this quote up against the wall. First my apologies as I can't recall the author. (I'll need to return there to write it down!!). Anyway, this is the quote:
"Never teach a child what he can learn for himself."
I do catch myself at times wanting to present an elusive answer thus rescuing my poor darlings from a bout of self-doubt, rather than sitting back and wait, anticipating that golden moment when the children have that 'a-ha' moment when they discover the answer for themselves.
