dd is 5 and a half wks, BF exclusively for last week or so, prior to that having odd bottle of formula from DP so i can sleep. since exclusively BFing i have noticed that right breast becomes engorged quite a bit more than left, and although DD sems to feed well from it amd it does seem to 'empty', it doesn't ever 'empty' like left breast. so i have expressed from it twice, once a few days ago with no probs, then yesterday. my breasts seemed to be completely empty by evening, DD drank all expresed milk, thne i latched her back on to both breasts, she latched on keenly but kept breaking off after a few minutes and crying. eventually gave her a botle of formula which she drained and fell asleep at midnight. (prior to last nights formula she had not had any for over a week and that was beacuse she was refusing it). she woke again at 5.30, fed from left breast, fell back to sleep until 7.30 when my right breast was visibly larger than left, rock hard, and still is hardly any different after her feeding from it (she is fast asleep again now)i'm reluctant to express from it because i don't want to perpetuate the problem, but then i'm scared of getting mastitis. also, the side of right breast is quite painful when she feeds. her latch is fine, my nipples are not cracked or sore.
