Hope I am posting this in the right place. LO is 8 1/2 months now. He has been sleeping through the night since 3 months old. Initially, I had engorgement overnight until my body adjusted. But all of a sudden yesterday morning I woke up with an enormous rock hard right breast. So engorged that LO didn't want to latch on. It was relieved a bit after nursing but it was still larger than the left for the majority of the day and never really felt empty (the top part is still a little hard). Now this morning both of my breasts were huge and rock hard and leaking - just like in the beginning days. After nursing on both sides there has been some relief though, but I thought maybe I have a clogged duct (which I have had once before and felt so much worse than this). So what the heck is going on all of a sudden? Could it be hormones? I think I may have been ovulating for the first time last week (EWCM and sore nipples and cramps). Could my changing hormones be causing a supply increase? Sorry so long!
