A hefty amount of it will be down to basic human instinct, it's not like you don't know how to breath; or you can't tell that hunger means you need to eat. The more complex things, like balance and language come down to knowledge learnt after birth.

And for 2; I find it disturbing that quite alot of people where i live are the same age as me and have kids, but they don't do it round here because they think they're ready. They do it because of the saying "It's like wearing a coat indoors"; which apparantly makes it cool to impregnate 16 year old girls.

I don't know anyone round here, who has had a child because "they think they're ready", they're just stupid. Litterally, mentally retarded round here (: But no, i don't think children should be braught up outside of a relationship that works. Get engaged atleast .
