Over the last three days my milk supply has gone right down but my DD's nursing pattern has not changed at all. She is 11 weeks old and feeds about 7 times during the day (I feed on demand but she generally feeds about every 2.5-3 hours during the day and then goes from 11 til 5.30/6 ish at night). I have one breast that is a lot more milky than the other and the milk supply in that breast in particular has diminished significantly. Nothing at all has changed to prompt this drop. Has anyone else had this experience? Any advice? I am at a loss.
