I'm from this area originally, and had my son at the hospital there. I've also worked with a lot of mums to be and, in particular, young mums.
The area as a whole has a reduced number of people even trying breastfeeding. Baby doesn't even go near the breast to see if it's possible. I'm all for encouraging breastfeeding - and these steps seem reasonable in doing so. They're not refusing to allow formula - just asking you to bring in your own.
Nappies aren't free in hospital. You take in clothes for baby. You arrange your transport home. If you want snacks etc in labour you bring them in. And this is an extension. I see the debate about adults getting fed - but it's not like they're forbidding feeding - they're encouraging an alternative and free method which will, in most instances, have a great benefit to both mother and child.
