Yearning to Gain

We were back at the pediatrician today, and unfortunately - she has lost even more weight.  We're now down to 7# 6.5oz.  *sigh*  Of course, I immediately started crying.  I need her to put on weight.  We're going back again on Thursday.  I suspect if the next 48 hours aren't productive we'll be headed down a path of supplements (which is another healthy expense).  I'm pumping and feeding often - she'll guzzle the pumped milk, but sits lazily more often than not when she's on the breast.  Of course, pumping I'm not getting a huge amount either, so that sits poorly with me.
