I agree with Lenore...4 oz is great! It took me about three weeks to get to 30 oz a day. I've heard that the Motherwear catalog is great inspiration for pumping. Once I had a supply saved up in my freezer, it helped a lot to know I was sharing milk with a little guy whose Mama had to postpone breastfeeding to fight cancer...She's now using my milk in the Lact-Aid!
