My baby is 4 months old and is typically a very good nurser. Last night she nursed from my L breast at 7:00 but did not nurse long before falling asleep. By the time she woke up, nursed the R breast, and it was time for her to nurse the L again, I was engorged. I have not had a letdown since 7:00 pm yesterday (13 hrs ago!!) And I am miserable. I let her nurse that side all night and pumped the other. I soaked in a hot bath, I have massaged, done relaxation/visualization with no success. Help please!!!
