Differences in breastmilk for boys and girls
I came across this research - they have apparently been able to identify that breastmilk is different for girls and boys - more fat and protein is found in the milk produced for boys. This really does show that our body is somehow aware of the gender of the baby we conceive, making adjustments for the extra nutrients boys require.

I am having an obsessive morning and have spent my time googling things like "lost weight before TTC" and out of all the hits I can find it seems that the vast majority of people who say they have lost weight before having a baby, did go on to have a girl. This LE diet looks more hopeful by the day to me!
