Cream peas...hmmm

We got some lovely cream peas at the Farmer's Market yesterday and John made some of them into baby food for JJ.  He wasn't exactly enthusiastic, but he didn't hate them either, so I'm considering that a "win."  We want to get more fats and protiens in his solids diet so we can transition him completely off of formula so he's only on breast milk and solids.  As it is, he get about 8-16oz of formula a day in addition to all the breast milk I can pump (when I'm working) plus nursing.  It's been a real struggle to keep his weight gain up - he seems to need more fat than he's getting from the breastmilk.  I suspect the issue is that I'm working - as a result, there are at least 3 days a week we're not working on keeping the production levels high, and the pumping doesn't do a great job of draining the good fats, unless I have him nurse first.  Who knew breastfeeding was such a tricky process?!?!
