It was evident that this photo was meant to be art (whatever that means). And the fact that it was shot by one of the world's leading photographers is meant to reinforce that claim. But while it is a powerful and strong image, it also shows that this image isn't 'feminist' as Claire Cohen, writing for the Telegraph, says, or a 'victory for small breasted women'.
Apparently 60% of men would consider being a stay at home dad. I find that men who were raised by strong career women have more respect for equality than those who weren't. I have friends who have shared six months each of maternity/paternity leave and friends who will argue that it should be a mother's responsibility. In a progressive society, nothing beats equality.
