dont't be disheartened by the general rules. Try to watch a comedy or listen to relaxing music and dont try so hard to pump milk. When your body is stressed, milk will be disrupted. 15 mins before you start to pump milk, try to use a warm (not hot towel) to open the milk ducts. You can also drink papaya fish bone soup, I know that helps alot for most mums!
Try again till beyond 10 days and see if your milk ducts will miraclous "open" and milk will be out.....!!!
Jiayou and dont give up!!!
