I regularly give talks and presentations to student midwives, midwives, doulas, and other maternity care workers. See here for testimonies. Some of my slides are here for you to use....there are links to Prezi slides, and shortly via SlideShare.
'Having a Baby' is a talk I gave at the RCM student midwife conference in 2014, on social media. Click on the image to take you through to the Prezi.
