It is really refreshing to read a nuanced discussion of why charities need to be very careful as to who they accept sponsorship from.
My take on it is this: organisations like IBFAN, Baby Milk Action, NCT, La Leche League have a huge influence on what formula milk manufacturers do because they have chosen to refuse advertising from these sources. They and organisations like them rely on this ethical stance when lobbying for measures like the Innocenti declaration and for its full adoption into domestic legislation. If, as a charity or similar organisation, you rely on a particular source of funding, then it follows that your actions can be influenced by threats to withdraw that. Sadly, the current example suggests that sometimes charities don't understand what they are giving away in return for tiny amounts of money.
Just to qualify this, I am a mother of an ex-27 week BF prem baby. Sick and prem babies do benefit from formula but much, much more specialised and sensitive support helping mothers to breastfeed those babies is necessary.
Ruby, do bear in mind that babies whose respiratory function is compromised or with other issues (eg cardiac problems) may need more calories than breastmilk can provide.
