I don't mean this to sound snarky, but seriously, why should I use a blanket? I can promise when I breastfed you would only see something if you happened to be really looking and staring while I was either latching on of the baby popped off. I am extremely modest and self conscious but yes, I breastfed pretty much everywhere and NEVER used a blanket. Main reason is my daughter would refuse to nurse under one but also they were very awkward and uncomfortable for me as well.
