I have a rotten cold and streaming nose and have had a couple of Lemsips. I don't know if the cold or the Lemsip has affected supply but my right boob seems to have packed up. DS (5 and a half months) gets very frustrated on it and has to be swapped to the left which is still fine. I'm also having a rather disasterous time weaning at the mo as he is completely constipated and miserable and I want to give him more milk to sort it out!
