Following on from entropygirl's posts, I think this is the point:
Breastfeeding is the biological norm. Therefore, there are no benefits of breastfeeding, but there are risks of formula feeding (which are well understood and not in dispute).
However.
The risks of formula feeding need to be compared and contrasted with (and this isn't necessarily the entire list):
- The risk to the baby of not thriving/starving if the mother is unable to breastfeed and donor breastmilk isn't available
- The risk to the mother of not taking essential drugs (of whatever type) if they are not safe while breastfeeding
- Other risks/issues which are individual and personal to a specific family where there is a physical choice whether to BF or FF (ie where the mother is physically able to BF). For instance, a mother who has been sexually abused may be psychologically unable to BF because it would be just too distressing for her. For instance. And many other reasons.
To state that formula feeding is a risk to health and that the NHS should not be supporting it is reasonable - provided that the statement is made in the context of the above (ie within a balance of other risks).
It's a linguistic detail which is important, though, because to put breastfeeding on a pedestal and to call it "best" implies that formula is "normal". While it clearly is "most common" it's not in any sense biologically normal.
So, this is quite different to saying that "a FF baby who would not otherwise have been able to be fed (for whatever reason) has been put at risk by being FF". That statement makes no sense. A FF baby who would not otherwise have been able to be fed would be at "somewhat" [understatement of the year emoticon] greater risk without the life-saving and life-giving formula that we (thank goodness) have available to us.
The baby friendly initiative does require no free formula available (except in emergencies, etc) but it also requires hospitals to offer more support for breastfeeding, in various ways. It's supposed to be a two-part scheme! It has been shown to improve initiation of breastfeeding, but not rates at one month, so there is a lot more community support required.
