i've heard that lecithin gets rid of blocked ducts right away. check with a lactation consultant maybe....also, since you're nursing twins, if one of the girls is a more vigorous nurser, make sure you're rotating them, even if they have a preferred side. once you get settled into a routine and no longer having trouble with blockages, it's probably ok to let them pick a side, but i definately found that one of my guys would leave some behind and i'd end up plugged and sore if i didn't switch them around at that age. they did eventually settle onto preferred sides, which coincidentally were the same sides as where they were inside...funny/spooky, no? they're still nursing at 2 years. not sure how or when this ride will stop!
