I think she has a point... HK people like to戒片 at early age... but most westerners do it naturally.
戒片 early= more convenient to care taker.
but no need to do it too early la... around 2 yrs is just the right time.
and every child is different ma.... some people tell me their child 戒片 at 15 months!.
my response is: SO?????!!! just more convenient to you ... it doesn't mean your child is smarter or something!
