This is EXACTLY what happens with my little one. Lots of fussing on the left breast - so we have also been doing football hold which has been helping somewhat. I do notice that she gets much more wind when feeding from the left and not so much now that we have changed things. I've also cut dairy AND caffeine (not that I had a huge amount of caffeine, just the odd cup of tea) from my diet and that has seen massive changes.
I do miss my hot chocolates though - but bubby's comfort is way more important than a small indulgence on my part!
