Breast size has no affect on breast feeding. Any sources to back up your claim?

This graph is useless because cup size ≠ breast size. Cup and band sizes go together to fit the person. A 34D is way smaller than a 40D even though they are the same cup size. Without the band size we have no idea what the real difference is. This video explains it pretty well: https://youtu.be/L9JZzPMHok8

Omg thank you for this!!! I never understood when whom would ever be used!!
