Teenage|Pregnancy., ... Options

[DaCandy]

About a week ago one of my best friends told me she was pregnant. She's 18 ( OK she's "legal" ) But i think she doesn't have the maturity that it takes to raise a child.
But she says she's happy and that she really want it.
While teens, don't we all girls, at a certain point, want to be moms ? Well I had that moment lol.
I just told her that it was going to be hard but if she was happy with it i could only support her.
She havent told her parents yet, And knowing them as I do, they wont be " that happy".

"You're 17 .. What you know about that ? "
Well I have two younger brothers and I had to take care of them and trust me it was SOOO NOT EASY .. Cuz babies do look cute and adorable (and they are) but they also pooh/pee (LOOL), have to eat and they cry alot !.
Anyway I think she's fantasizing about being a mother, she works and he has a house, but its like under his parents' house and they dont like her much.
And i can see it coming .. You can say I'm being negative but I know both of them and I know both of the families, and I can feel that in future things will not work as she expected.
She'll end up moving to his place, because of her parents, and even when you're in love living with someone its a huge step and especially when we're young things don't really work out, cuz its too much, plus she is going the have a baby and stop working and he'll have to find a job to support both + the baby, HE'S IN HIGHSCHOOL and never worked in his life. I have so much to say that I could stay here all night long.
But anyway ... I think it's too soon for her, and she's not seeing the both sides. But I'm her friend and I wish her luck.

Mais ... What would you do in a situation like this ?
