I need some advice about what pump is best. My DS started sleeping through the night last week but I noticed a decrease in my milk supply since I was going 12 hours without feeding him. I've been pumping before I go to bed and once in the middle of the night to try to keep my supply up. I've been doing this for about a week. Now my nipples are sore ALL THE TIME and they feel like they are going to explode when I'm pumping. I use a Playtex Embrace pump. Do you think I need a different/better pump? If so, is it possible to by them used somewhere? I can't really afford to drop a couple hundred dollars on a new pump right now. Any advice would be greatly appreciated!!! I can't stand nursing my son right now because it hurts so much and I hate that! Thank you ladies.
