Oh, I am so sorry. In 2005 I had induced labour at 21 weeks - our wee girl had anencephaly. I was very scared and worried, but honestly (and I know this sounds strange) it was an oddly nice experience in the end. We cried a lot, and were really sad before and after, but having her, and holding her, and being able to see how beautiful she was, and being able to cuddle her and say goodbye to her was wonderful - can't type for tears now, mind.
I also am glad to have gone through labour and birth with her - makes me feel properly her mother, and links her to her sister and brother who were born after.
Practicalities: induction can be a bit sore, and it can take a while. Be prepared. Take books, sudoku, magazines, etc. And take a camera - we didn't, but the mw took pictures of dd1. In hindsight I'd have liked pictures of us holding her.
Your baby will be very tiny, and very skinny and red, because fat hasn't been laid under the skin yet.
Not sure what else to say just now, but please do ask any questions, and keep posting and talkiung here.
