Anyone else still nursing with a shield?

I love the fact that I'm able to breastfeed my daughter because I wasn't able to with #1. It's a huge accomplishment for me and I want to stick with it as long as possible. My biggest frustration is that I still have to use a shield to feed my littlest love without feeling pretty unpleasant pain. I feel like I'm not doing something right but no one has been able to successfully guide me down the right path. I guess what I want to know is that I'm not alone. Anyone else in the same boat as me?
