I have been bf my son for 2 years 1 month, he is an enthusiastic breastfeeder and has shown no sign of wanting to give up. We co-sleep and he feeds a lot of the night, as well as evenings and mornings. I work 3 days and don't express any more but the other days he feeds during the day on demand. Recently he has been saying 'no more milk mummy' or 'little bit milk mummy' when feeding and getting upset, even though when I squeeze there seems to be milk there. My breasts do feel a bit empty. Could my supply be diminishing and why would that be when he seems to be feeding as much as ever? How can I get my supply up again to meet his needs? I really really don't want to get into expressing again, and can't do it at work (just don't want to get into discussions about extended breast feeding for one). Has anyone else had this experience? What did you do?
