I don't have as much as a leaking problem but when I'm feed on one side the other leaks a lot - I also express for Joel a few times a day.

I was told the supply settles down to meet your babes sucking demands and they don't get so hard and sore ...always enough in storage though.

Mine have settled from first week but when boys still in hospital overnight - they did get hard and sore in the middle of night when I waking to express anyway and 1st thing in morning before I went to hospital.
