reethie, the WHO web-based documentation is difficult to negotiate. They don't always update, and older stuff remains hidden away, but pops up sometimes when you are searching for something else.
The current info is in the Global Strategy, which is an international document, for gloabl application.
It calls on governments and health services to set in place a number of systems, and I quote from just a small part of it:
"33. With these considerations in mind, the global strategy includes as a priority for all governments the achievement of the following additional operational targets:
? to develop, implement, monitor and evaluate a comprehensive policy on infant and young child feeding, in the context of national policies and programmes for nutrition, child and reproductive health, and poverty reduction;
? to ensure that the health and other relevant sectors protect, promote and support exclusive breastfeeding for six months and continued breastfeeding up to two years of age or beyond, while providing women access to the support they require ? in the family, community and workplace ? to achieve this goal
(Note the inclusion of the word 'all' which I have bolded here)
There may well be other documentation to support the application of the strategy in specific contexts. It's obvious that the risks of serious infection or under-nutrition would be much less in the developed world, but breastmilk remains a nutritious drink wherever it is given, and a loving part of a close mother-child relationship. In addition, longer-term bf like this offers protection against breast cancer for the mother, so it has this benefit as well.
