We've been giving DS (seven months) an occasional bottle since he was six weeks old, and I've never had much trouble expressing plenty of milk for this, though I suppose the amount I've got has very gradually gone down over time. However recently, I've just got less and less and now I can't seem to get a letdown when expressing. I get a little bit that's just squeezed out, but not that gush you get from a letdown that fills most of the bottle!
I work three days a week and it's a constant struggle to get enough milk to give to the nursery. If it carries on like this I'll have to let them give him formula, which I really really don't want to do. Does anyone have any hints for improving my expressing, please??
