I'm planning to phone the NMC tomorrow but I reckon you guys will be just as knowledgable anyway!
I'm a paediatric nurse but a job has just come up as a nursery nurse on the maternity unit which I'd really love. Obviously it's a lower band and no nursing qualification required but I wonder, if I went for it, woukd I still be able to do my PIN on the basis I'd be working in the hospital and continuing professional development etc. I'd like to do this for a while then possibly apply for Heath visiting but ideally I'd like to not have to do bank work to keep my Pin up as well 
TIA!
