Check out this awesome advice to new mothers. I especially like the way that she acknowledges you may not actually perceive these differences, so you should look for them:
Boy or girl? That’s the first question people ask when they hear you are having a baby. And according to child psychologist Dr Pat Spungin, the answer makes a huge difference to your baby’s personality and progress, from the very moment he or she arrives in the delivery room. ‘Gender affects everything – from how well babies make eye contact in the first week of life, to whether they’re easy to potty train at 18 months,’ she says. The differences are very important for parents to be aware of, yet it’s so easily overlooked.’
The amazing thing is that the full article actually acknowledges the ways that parents’ reactions shape the children, and the ways that parents differentially classify the same behaviour in boys and girls.
I particularly liked the closing line (after explaining the boys are unsociable, slow to potty train, slower to talk, etc).
Does it all seem weighed in favour of girls? Not in the long term. Your son is likely to earn up to 25% more than most women, be bigger and stronger, and has better odds of becoming Prime Minister. Plus he is less likely to have to worry about domestic chores (apparently, there is no society where men are the primary caregivers). Oh, one more thing about a boy. He never stops loving his mummy.
