Well I only have a 13mo son so won't be buying him one.
Cynically I know they are only doing it to chase higher sales figures and more PR, not because companies like this actually care about the long lasting psychological effect regarding body-image that dolls like these have on impressionable young girls.
However, new attitudes like this from influential brands may filter through to mainstream, and we may see more diversity in modelling, advertising, girl bands and other areas that traditionally promote eating disorder level thinness, white skin and silicone enhancements.
So, long time coming and bravo!
