I hasten to add, this is hypothetical atm, as I don't know what I am having, boy or girl!
But for the last 6.5 years I have dealt only with girls (I have two dds), and I am thinking that having a boy may be a big shock - maybe not at the newborn stage, but further down the line.
Are they really so different, or is that a fatuous remark from an ignoramus? I simply can't imagine myself with a baby boy.
