"This book is the essential guide to nutrition for women who are either planning to conceive, are pregnant or have given birth. It will also help women who are having difficulty conceiving or taking their baby to term. Top nutritionist Patrick Holford and Foresight practitioner Susannah Lawson start with a pre-conception nutrition checklist, moving on to cover nutrition in pregnancy, complete with diet and meal plans, and follow up with useful advice about your own nutrition in early parenthood - from beating the baby blues to how to produce the best-quality milk. The final section deals with optimum nutrition for babies and young children, with information about weaning, prevention of allergies and the ideal diet for a healthy child. "

I haven't read this myself but I hope it'll be useful to someone else.
Happy travels!
