Avalynne weaned herself much to my disbelief, lol! She just started freaking out at a certain nursing, and after 2 days of pretty much not eating, I bought bottles & formula. She would just do 1 bottle a day, and gradually went up in bottles and down in nursings for 1.5 months. I stopped nursing 100% just before she turned 6 months. She is now 7 months (yesterday), and I'm finally dried up. I think I've been completely dry for a couple weeks now.
So it took a good month & a half to dry up completely for me. I was really lucky though that she weaned slowly... I've never been engorged before. I can imagine it would be painful though! I've been full before when she missed a nursing, and that was sore!
Hope your boobies feel better soon!!
