Re: Need help to fatten up baby.
I agree with the PP that you should find a lactation consultant to check him for tongue tie or anything that might be keeping him from nursing effectively. The problem may be that he just isn't transferring the milk that you have. A lactation consultant can do a pre- and post feed weigh to see what he's getting during a nursing session.

WIC has pumps that they give to mothers--usually working moms, but who knows. Can you get one from them?
The Avent Isis manual pump is pretty effective and only about $30. And a lot of women have a lot of success with manual expression. Here's a link to find out how to do that: http://www.kellymom.com/bf/pumping/b...ps.html#manual
