Hun I know this is the EE thread but please don't think you won't be able to bf next time around. I will be trying with all of my heart to avoid EEing. But if that's how things end up with a new born I was expressing every 2-3 hours. I eventually got to every fours hours that included overnight tho. 30mls is quite good for early days! I remember being so excited to get 50, then 80...then eventually I would get 300. I took motilium pretty much the whole time. The thing is taking it only works if you remove the milk you make so you still need to pump regularly, otherwise your body thinks you don't need the milk you are making.
Good luck, take a look at the whole thread there are some very good tips in it
