I was 19 when I fell pregnant, and I got offered the programme.
I didn't want to take it, i live with my OH, I do not consider myself a "teen". But i signed up to it. I found it Hugely patronising and offensive. I told the nurse this, who stopped giving me the paperwork and just comes fornightly to see how we were. She comes once a month now if that, and its to weigh him, have a cup of tea and check he is progressing well. Luckily my FN was really sweet and realised I didn't need her help and backed off a lot.
At the end of the day though, i have called her a few times, she checks out rashes, helped me get the right help when he had severe reflux, and the weighing was so helpful in those first few months. I would rate it in that sense. if you think you can put up with the paperwork and stupid pictures and "feelings" stuff then i'd go ahead. Its free help a lot of people aren't privileged to recieve. and just someone else to talk to, makes you feel like you are not alone. I spend majority of our visits bragging about all the stuff he can do! Most people would get bored but its her job to listen haha!
