Thanks Belfie and Melbel. I think you've both given me some really helpful advice and some confidence to persist with expressing.

Belfie - my bub is about 2 weeks old and I get about 80-100mls every 3 hours with a 15 minute double pump. A week ago I was getting about half that. I'm hoping that it continues to increase as I know that he will soon need more. I top up with formula maybe once every couple of days as I don't quite have enough to get through each feed - just depends on how hungry my little man is.
