My daughter (who doesn't really do social media) had an emergency c-section for a brow presentation three years ago, with a successful outcome for both mum and baby. She is now 20 weeks into 2nd pregnancy (all going well) and has agreed to take part in a study which is investigating evidence that a 2nd pregnancy may lead to premature labour if the 1st pregnancy resulted in an emergency c-section during the 2nd stage of labour, when the baby had to be extracted from the fully dilated cervix. Has anyone had experience of this scenario, as this is something that neither of us has heard of previously?
