O.L.
First off, what a great gift to give to an adopted baby! My younger sister was adopted and had a milk allergy, so it probably would have worked perfectly for her if my mom had known back then that it was possible.
Here's a link that might help...

There's also a really helpful site w/info about galactagogues and other tips for increasing supply...
www.mobimotherhood.org (they also have a group on Yahoo).
Best of luck to you or whomever it is that's thinking of doing this!
