I've been experimenting with expressing but I'm struggling. I'm using a Philips Avent electric pump and I can't seem to get a good seal around my breast and the let down reflex doesn't get the milk flowing or seem anywhere near as powerful as my baby's sucking is. I've got small breasts and even smaller nipples! Does anyone else have this problem and/or a solution? I need to go away for a day working soon and don't want to resort to formula to feed bubba just because I can't express.
