Whoa this whole topic is a headspin.
Ok in regards to limiting the availability of formula, I really can't understand how that's fair. Can you think of anything worse than running out of formula for your baby and having to trek across the city to access it? What about if you run out in the middle of the night and it's only available from stores that are open office hours? It's all well and good to say that as a theory but the practical implications for women who were forced to or chose to formula feed are enormous, and I do not think it's fair to inflict that upon them. I agree with the comment that parents would resort to more readily available milks that aren't suitable for babies at all.
Also, how exactly can women not have the right to feed their babies how they wish?! Are we going to start legislating how women can birth? How they can soothe their babies? Where their babies should sleep?! I can't fathom the absurdity. Shall we ban the sale of cots and basinettes and force all women to co-sleep whether they want to or not either? Ridiculous.
In regards to vaccination, the arguement is that if your child is not vaccinated they can pass the disease onto other children. Whether a child is breastfed or not only affects them.
It really seems like the mothers who formula feed are on one side of the fence and the mothers who breastfed are on the other. Well I've been on both sides of that fence, I'm struggling to breastfeed after successfully breastfeeding my first born into toddlerhood. And from my personal experience, having to prepare bottles and always be sure of having enough formula is incredibly stressful. I've been caught out having left DD2s bottles at home when I've been out running errands and having to buy a new bottle and a tetra pack. Imagine if formula was only on script! She would've had to starve until I got home (which takes HOURS on public transport btw). So really, lets be practical here. There are better ways to encourage women to breastfeed.
Also, as far as "the majority of women can physically produce milk" there's a bit more to it than that. It's also up to the baby to be able and willing to latch. Obviously babies have the natural instinct to do so but if a baby has a clef lip or palate this can prevent breastfeeding, or if a baby has a high palate as mine does. What about women who return to work but are not able to successfully express? It's very, very easy to see breastfeeding as black and white when you're able to do it, when you're on the other side of the fence dealing with (possibly) your own feelings of guilt and (definately) the judgement of other people who've never been in your situation, you can see it is far more complex than it appears.
