No not intentionally but they have done new research to suggest if you eat breakfast cereal daily you are more likely to have a boy.
Also I read whilst TTC'ing that BD'ing on the day of ovulation is more likely to result in a boy, as the male sperm are quicker than the girls, whilst the girl sperms can last longer (hence BD a few days before ovulation and more likely to have a girl).
I bd'ed only on the day I ovulated - not for any of the the reasons above, but because I ovulated so early and wasnt expecting it so quickly - so missed the other fertile days!
I also have always eaten cereal for breakfast!
We are having a boy!
Probably all coincidence, but interesting all the same!
