Re: breast flange too small or too big?
It sounds like your milk supply has evened out, which is very normal at 6 weeks. You may need to go down a size with the flanges. If it's hurting and dragging more of your breast in there, especially. I also think it's ok to have different size flanges on each side.
On one side, I am now 3 flange sizes smaller than I needed at the very beginning and four flanges smaller on the other side. I had oversupply and was very very engorged at the beginning.
