I can't get through the full thread, but the 'stupid fucking law' that 'discriminates' against formula feeding parents is also in place to protect formula feeding parents.
There were cases where prior to this law stores that ran promotions on first stage milks ran out of them (in Australia if I remember correctly) and parents were forced to switch new born babies milk brand which is recommended against because of risk to baby.
Formula promotions would effectively penalise poorer people as anyone who can't afford to bulk buy misses out or if parents can only afford to walk to the local corner shop have to pay full price rather than get 3 for 2 or something at the big tesco's.
There are a number of other ways it protects ff parents but I forget off the top of my head. But this law protects all parents, and babies, it doesn't 'discriminate' against formula feeders.
Milk is essential to life for infants, if they are not being bf then that makes formula essential to life, like prescription medicines are, and we don't promote prescRipton medication via store points etc, it's no different.
