2 great books especially for those doing Perinatal Yoga
"Pre-Parenting. Nurturing your child from conception" Thomas Verny & Pamela Weintraub - a fantastic update to 'the Secret life of the unborn child', full of recent developments in neuroscience and developmental psychology translated into practical advice & insights. Good for those doing Baby Yoga too.
"Birth. A History" Tina Cassidy. The terrible things visited upon women with the emergence of early obstetrics makes for a grim read - not a suitable read if you are pregnant! However, it does put perinatal care into a historical context of how we got to the present and where figures like Lamaze fit in. Written by an American it does have an American bias but has lots of reference to the UK and other parts of Europe.
