at this age Vick, my two were on their jolly way to stopping feeding altogether...so we were down to one side only (their preferred, the left) period.
also, my kids never bit me...or at least only tried to nibble at the end of feedings, which was by accident or in Oscar's case, a cruel joke....he used to laugh! They both had 16 teeth by the time they self-weaned...but then they were never the type to want to "soothe on the boob" so perhaps its the non nutritive sucking thats causing the pain rather than the feeding per se?
Big hugs on the pain, hope it heals and you enjoy your hols.
K's mum- best of luck over the coming weeks and months xxx
