Also probably has something to with whether you yourself feel/felt mature enough to be a parent at 21 (or whatever age, for that matter) would probably make a difference in whether you think another person is too young to be a parent at that age.
I guess if you tell someone you had your first child at 18, they would probably try picturing themselves at 18 with a child and thinking that they would hvae been way too young then and not ready emotionally, financially etc. I definately dont think that being a teenager or early 20's means youre too young, because its about whether you feel mature and ready enough, not when the girls from school , work , family do/did.

I am 20 and want to be a parent very much, and i definately think i feel ready. I have talked about this with David (my DF) and he wants to as well. He is a bit older than me (32) and doesnt say I am too young. My school friends, however, think its crazy and say that i am too young to get married, buy a home, have children and all that. I am not sure why because when I ask, they cant explain why, but i thought it might be because they havent yet done or dont want to do those things in their lives yet. The people i went to school with are all older than me but I just tell them I have been out of school for 3.5 years - i have qualifications, a well paying job, just bought a home and getting married later in the year. Out of my "group" at school i am the only one that has done all those things, and none of them before i was ready to.
So basically, i guess its just your own perception an how you feel about it.


Sorry, big rant there
