not sure yet- but I hope everything goes well for you. Try to find some support (maybe join a breastfeeding group or something) so that when the baby is born you are giving yourself every chance of success.
It was easier the second time around. My problem the second time is that I had way too much milk. I had to pump off 30oz a day just to keep his colic under control. It's a good thing I'm having twins this time, lol.
