All of my dds love barbie. I however, like to point out to them at every possible opportunity that REAL WOMEN DON'T LOOK LIKE THIS.
Germaine Greer writes brilliantly about it in The Whole Woman. Basically, Barbie started life as a German porn doll, marketed at middle aged men and sold in newsagents. Her vital statistics are incompatible with life (ie, there isn't enough room in her abdominal cavity for all her vital organs) and with feet that size in relation to the rest of her body she couldn't stand up.
And yet, all this seems to fall on 3 small pairs of deaf ears...
