Have stopped bfeeding 16mth old. He was down to 1 feed at bedtime. Have fed 2 others with no probs stopping. Both breasts over a week later are v painful. Both feel lumpy esp under the nipple and are sore and tender. I don't feel engorged as in rock hard boobs, I am not unwell as in mastitis and it is both sides. What could it be? And how can I help it?
