i feel the same way too! but it is untrue when i pumped it out. why not u buy a nursing pillow? it helps a lot when my arms are tired.At times when my breast feels soft but baby need to feed again, latching really makes me feel I dun have enough supply. But if I use pumped out milk can tell slightly meeting demand as my girl taking 50ml for 2-3hrs. I can pump 50-80ml in 2-3hr. Dunno how to overcome this feeling. Also latching is making me more tired.
