... and more scientific than the usual methods that people claim to be reasonable methods of predicting the sex of a baby.  Here's a somewhat lengthy excerpt from a recent article in the Economist ("Sugar and Spice", Apr 24, 2008):

"Although a child's sex is genetically determined by the father, mothers
can influence the development of one sex rather than another. Studies
in animals and humans suggest that there are links between the sex of a
child and the mother's diet and her levels of stress. Although the
mechanisms are not well understood, this appears to have evolutionary
roots which favour greater reproductive success. Hence in hard times
when food might be scarce, daughters were more valuable because their
chances of providing offspring would have been greater than sons, who
might get killed or fail to find a mate. But in good times sons were a
better bet because they could father more children.

Those same evolutionary influences persist in modern life. New research
shows a clear link between higher energy intake around the time of
conception and the birth of sons--especially by mothers who eat cereals
for breakfast.

The study, by a team of researchers from the Universities of Exeter and
Oxford, looked at the eating habits of 740 British mothers expecting
their first child. The overall sex ratio of their children was close to
50:50. But when split into three groups according to the number of
calories the mothers consumed around the time of conception, the
picture changed. Of those with the highest energy intake, 56% had sons,
against 45% in the group with the lowest calorie intake. Moreover,
besides consuming more calories the women with sons were more likely to
have eaten a higher quantity and range of nutrients, especially
breakfast cereals."

Esen forwarded this to me today because I eat cereal almost every morning for breakfast (or maybe because he just thinks that I *clearly* fall into the high calorie intake group... he did make a snide remark about my increasing body mass just the other day).  I'll eat toast if we're out of milk or occasionally eggs on the weekends (particularly if he cooks them for me!), but I'd say that I eat cereal 95 percent of the time.  Guess he thinks we're having a boy, although I'll leave it to him to come out officially with his guess.
