Alternate title: "Should my boob hurt this much?"

LO is 16.5 months and was down to two nursing sessions a day (morning and before bed). It really started to seem like she didn't really care so I started occasionally skipping sessions and she was fine. Then I started to notice I wasn't always feeling the let-down, so I figured i'd just stop and see what happened.

The first week was fine. LO didn't even notice (I was a little hurt). My breasts felt a little full, but I figured it was going to be easy. Not so! Yesterday I started feeling pretty sore, especially on my right side. It's not like a horrible pain, but if I bump it (or if LO kicks me in the boob - why does she do that?!) it really hurts. It's also feels a little (TMI) lumpy. Is this normal? It's a lot like when I first started nursing and my supply hadn't regulated.

Any advice from moms who've been there? I'm assuming there's another thread out there about this, so if this question has already been answered, can you point me to the link? Thank you!!
