first off:
i have NEVER suggested just throwing a kid into primary school without any kindie in chinese.
secondly:
many local (even the chinese-language ones) that have western kids send notices home in ENGLISH, if requested. now, i realise that this is not true in all cases, however, if you search for it, you may be pleasantly surprised.
thirdly:
in no way do i think a local school is perfect or perfectly suited to all people... i DO think it is unnecessary to completely disregard them. if you look around AT KINDERGARTENS (that is what the OP is asking about after all!) you may find something local that will cater to your needs, have a space available AND not cost an arm and a leg to send your child!
lastly:
for primary school, i HAVE MANY reservations about sending my kids to a local school... however, as we just can't swing the school fees for any of the "western" schools.... $6k/month, plus uniforms, bus, other expenses...local is it... now, if we find that our kids are having a difficult time coping, then we will look at other options.
PS> yes, my husband speaks chinese...but that only plays a small factor in our decision. yes, we have his family here, but we do not live with them nor do my kids see them every day... sometimes we go weeks without seeing grandparents.
PPS> as for K2 jumping from 4 strokes to 20... my son is curently in K2 and they are not doing 20 stroke characters... maybe 5 strokes...but not more. they are NOT even writing full words yet (in english), but still working on single letters/numbers.
