She does have a choice - yes her age and many many other things will be a barrier, but it is do-able.
However she does need to know the reality of how hard it will be, and will always be - as a young mum.
Choices made now will echo through her life, in ten, twenty years when she gets asked 'oh so how old were you when you had your child?'
I am not saying they are in any ideal shape to do this but they do need know the realities of being teen parents and that she could end up resenting her own mother if she feels pushed in to this
I was pregnant as a teenager. The father should have been in prison, say no more / he wasn't around
My mother tried to heavily coherse me into abortion and rang around private clinics and even booked me one without my consent - i told her no and she asked me to leave the house the same day - she said she felt concerned she didn't want a screaming baby around.
Sitting alone in the homeless unit of the local council aged 16 is no joke.
I lost touch with everything and everyone I knew. Whilst my friends were going on to sixth form / working summer jobs in ibiza, I was stuck at home changing nappies
Reality was, no one wanted to help with childcare so couldn't get a 'real' job (other than a couple of working from home roles for pennies) - until my kid went to school. Then I was very limited to working during school hours
And that is how it was until my kid was a much older child.
It is a decision she makes now that will affect every aspect of her life forever
