I recently did some interviews with the breast pump development company Medela for their revised website. The information on the revised site is really good and is all evidenced based.
They have set the information out on a timeline starting with pregnancy through the first 6 months of your breastfeeding journey. You can pick out the sections relevant to you at the time or check out the whole lot. Its all there.
Here it is my breastfeeding journey
This ebook developed by Dr Vanessa Sakalidis and Dr Danielle Prime is really fantastic- love their work!! Danielle, Vanessa and I worked together at The Hartmann Human Lactation Research Group where they both studied and contributed so much to the global breastfeeding knowledge base.
