I respectful disagree, if you a re weaned from the shield going back on is not a good idea. Shields are bad for production. So a pound in four weeks basically. Ok what about the diaper output? Let me find some links, but I would nurse as much as possible, work on a deep latch, with the nipple sandwich technique and watch diape r output. I think it's going to be a fairly nerve racking few days but I wouldn't think that your supply is horrible damaged at this point.
