So the vast vast vast majority of new mothers produce milk when their babies are born. I think we all know that. (I hope we all know that.) It's free, plentiful (after you get going initially), and studies show its the best thing for your child to eat in those early months. Many mothers still opt to buy formula to feed their children instead. Quite frankly, bottle feeding is just easier, especially in that first few weeks.
New York City hospitals are trying stop new mothers from bottle feeding. Their approach is to ban advertisements and stop the giving away of free formula packs at their hospitals. I've got to scratch my head on this one. The milk that's free anyways will be used more often than the formula that has a free sample up front and then massive costs down the road just because that initial free batch of formula is no longer available? Somehow I doubt it. What you feed your kid is your own business provided you're not seriously endangering them. But come on! Are you really going to switch because of lack of sample packs and posters? If so, then maybe you should shelve that idea to become a parent for a while.
