I think, after having 3 of each, that boys are just mostly boys and girls are mostly girls. There are behaviors that seem to just come about, patterns of development that are for some reason pre-programmed according to gender. Girls are faster at their fine motor skills, boys run better sooner. That kind of thing. I'm lately discovering that some girl and boy behaviors are purely situational from a very early age...
My baby girl, Miss two years old, likes bugs. She likes snakes, lizzards, "bug-bugs" of all kinds. I mean she has so little fear of crawly things that I'm in constant fear that she will bring me some kind of extremely toxic thing one day -- open her little hand right under my nose, "see momma see my new bug-bug?!" just in time to see the scorpion sting her palm, or the tiny baby snakey strike her on the wrist. Ack!
We have a home day care business here, where as of today we have one little boy (he's about 5 months older than my baby) who joins our family during the day. He gets "home" (as my kids put it, lol) around 7:30am and leaves around 4:30pm Monday thru Friday. He was on vacation with his mom and big brother last week, and boy did our Izza miss her Davy! All week long she was catching "wrasshoppers" and "ugly bug-bugs" and trapping poor unsuspecting earthworms in all kinds of containers, "so i tan show it to Daby when Daby tums home!" She was diligently giving the snakes we have in glass containers "a drint of water so Daby tan see my sakes when Daby tums home." I quit counting the stinkbugs she caught, bare-handed, after she brought me the fourth one, "see momma see my tinky bug I save it for Daby!" Just so you know, a coffee can full of stink bugs is really REALLY nasty.
So anyhow, this is Monday and "Daby" is back. Joy! My drowsy kids finally arise around 9:00 and we all have breakfast, then the little ones and I retire to the front yard to play...I was getting my camera ready to take some very cute pictures of Izza proudly showing off her bug-bug collection, when I heard a peircing scream from the sidewalk in front of me: "AAAHH!! BUG-BUG!!! AAAHHHHH! MY DABY GET DAT BUG-BUG! AAAHHHH" My little bug collector, future entymologist prodigy, who has spent the last week with bug-bugs in her very pockets, is running screetching down the walk at the sight of a tiny little black beetle the likes of which she spent the last week feeding to her pet snake. And SCREECHING FOR A LITTLE BOY TO COME AND SAVE HER!
