DO NOT USE IT. The feeding advice in this book is not only dangerous, but it is directly contradictory to the feeding advice of EVERY medical and breastfeeding organization in the world, including the World Health Organization, the American Academy of Pediatrics, the Canadian Pediatric Society, La Leche League, American Academy of Family Physicians, etc., etc., ad infinitum. These organizations ALL recommend that babies should be fed a MINIMUM of 8 times a day and should be fed ON DEMAND.
