Boys Vs. Girls

I read this in an article in parenting, and thought it was so interesting and true from what I've seen so far. I wanted to relate it back to my kids...
1. Baby boys are 8x more likely to be born with a hernia. Sure enough, JJ had one, Boo did not
2.Infant girls feel pain and are more likely to cry than boys. Boo definetly cried more, she had colic, and things bothered her much more than JJ
3.Boys don't hear as well, but can better tell the direction of the sound.
4.Girls produce more oxycotin, making them more cuddly and involved in more caring play. JJ seems to cuddle more than boo. He is always kisssing us!
5. Boys play different, there is more banging, hitting, and playing rough. This is so true. Boo would read stories, and watch tv, and do relaxing things. She would study everything. JJ never takes time tothink he is always moving, playing, racing around, and pushing things.
6.Girls reach 50% of their height at 20 months , boys at 24 months... JJ isn't 24 months yet, but Boo should be 5'6-5'8 (I don't have her measure at exactly 20 months)
7.Girls speak sooner. An 18 month girl speaks 90 words , a boy 40. Boo said20 words by age 1, JJ still hardly says anything.
8.Girls potty train average of 35 months , Boys 39 months...Boo was around 36 months, maybe a little more. She started around 18 months though~!
9. Women pregnant with a boy consume about 10% more calories than with a girl. Boys typically weigh more. though Boo weighed 2 lbs more, I only weighed 2 lbs less with JJ! I did eat a ton more w/ JJ!
