I have been reading the book that I purchased, and it is absolutely BRILLIANT!!!. I dont think it forgets to mention anything. It mentions problems that some mothers may have that can affect milk supply and how to be patient and overcome these. It goes into the nicu unit, explains all the different feeding methods, different needs for different ages, expressing etc. I am in love with this book and would highly reccomend it. It has made me feel secure in being able to successfully bf the twins. It also talks about HOM's as well.
"MOTHERING MULTIPLES Breastfeeding & Caring for Twins or More"-Karen Kerkhoff Gromada, 3rd revised edition.
