A friend and I were recently wondering if there is some kind of statistical anomolyinvoloving friends and acquantences having the same gender babies around the same time. I just had a boy and my two friends who've had babies this year were also boys. When my first was born it seemed like everyone was having boys. OTOH my middle son was one of only two boys in his playgroup of eight or so, and the other boy had a twin sister. Obviously it doesn't apply on a large scale, but it will be interesting to see how it works out for this community.
