Breastfeeding - Is There a Randomized Trial?

I think that there is an increasing recognition in the world that some of the ways we have been pressuring people to breastfeed have been counterproductive and can actually be quite harmful. My general takeaway is that the effects are relatively small. And as a result, a big part of this decision should be about what works for you, what works for your family. How valuable do you think it would be to run a randomized trial to help answer some of these breastfeeding questions? I Think it would be very valuable.
