ive had sore nipples for around 4 weeks now, at first i though it was because DD (15months) was sick and i was letting her feed more often, but 4 weeks later and there still sore, its hurts like buggery when she attaches so im not sure if its a sudden attachment issue, i dont think its thrush..or could it be?? they hurts to touch, in the shower etc.. tjhey seem a little more red than normal too, but TBH i dont really take that much notice of the colour
