I got pg at 16 (had dd1 when i was 17 and a half) - not a good idea. Dd1 wasn't planned and i have managed but theres no way i'd have planned a baby at that age.
I will list the reasons i regret having a baby so young if you like and you can show them to her?
I was very lonely - im not a naturally lonely person before pg i was very popular but once i'd had dd i didn't have many visitors once the novelty wore off. I couldn't go to m&t because i was looked down on and pitied.
My mum told me not to expect any help from her so I couldn't go out whenever I liked because there wasn't always a babysitter - I spent my 18th birthday in on my own for this very reason. (my mum has supported me at times when ive been very low but she couldnt give me money cus she didnt have any and i cudnt always have her time because she works full time)
I had no money - i really do mean NO MONEY, i never went out because i couldn't afford it, i could barely afford all the things dd needed which made me feel like such a failure.
I will NEVER know what its like to be an adult without children - I won't know if i would have gone travelling or gone clubbing in ibiza or snowboarding or had a high flying career. I don't know if I would have chosen to never have children.
Housing and benefits is a NIGHTMARE - it honestly isn't easy to get money - they don't owe it to you, its catch 22 constantly, can't work because you've got a baby, no qualifications, no experience, no transport.
Until you are 18 benefits agency expect your parents to finacially support you and baby - i got £40 a week to pay my bills, food and everything dd needed until i was 18 then it went up to £80 - still nothing compared to what you could be earning and the waiting around in the dss is depressing, they mess your payments up all the time you can go in there on your knee's begging and crying and it won't make any difference - and why should she get this help for putting herself in this situation unless her boyfriend is very clever and can earns loads of money - even if he does theres absolutly nothing to say he wont walk out after finding out its not a bed of roses there she is left on her own in a rough area with a tiny baby to support with £40 a week - not a situation i'd CHOOSE to put myself in again i can tell you.
Even the strongest of relationships can crumble under the pressure of a new baby even when you are both mature enough to handle it. I'm on my 3rd serious relationship since having dd1. The first was with her father who turned out to be scum even though he promised he would stand by me and support me - he never brought her a thing and wouldn't come and see her on her first day home because it was raining - he had just turned 20 at the time (immature wanker). The 2nd could see i was vunerable and he took full advantage and abused me it took 3 yrs of counselling to get over it. The 3rd is an angel and has made my life right in so many ways but it would have been so much easier if i'd set my life up first - nice bloke, nice house, nice car, a few nice holidays etc then brought children into that. Rather than the rough area, damp flat, no money, abusive boyfriends etc etc etc etc
I really would lend her a baby for a few days and see how she likes it.
