This depends on you: your current knowledge, and professional situation. For advice, you can ask at the Community Forum. Your question will be seen not only by Health e-Learning's trained staff members, but also by your peers in the lactation community, including a lot of Health e-Learning's prior students who have been through the courses themselves. This means that you'll hopefully get a highly balanced view from many different points of view.
Any information you can provide about your experience will help you get a better-tailored response, for example, if you are an LLL Leader, a midwife in Australia, or just have a keen interest in Breastfeeding. Also be sure to read to see if anyone else has asked the same question!
