I have a baby who's just a few weeks old. I try to pump bottles occasionally, so that my baby will be used to the bottle, and also so that I have some mobility if it's really necessary. I'm having a difficult time deciding when to pump, though. I've found that the best time to pump, really, is right after I skipped a feeding (by giving a bottle). This is not always possible, though. Otherwise, I usually pump about a half-hour or so after a feeding, as I'm afraid to pump too close to the next one; I don't always get very much this way, though. When is the optimum time to pump?
Also, I've been pumping for about 10 minutes at a time, 5 min each side. Is this recommended? Does pumping longer mean I'll express more, or once my milk slows down/stops am I not likely to get any more? What's the average time I should spend on a pumping session?
