Yes, powerade helps the body build muscle, i drink it after long runs (10miles+) to help refresh my legs. I have a friend whose little girl had to have chemo and they managed to keep her weight on with drinks like sustagen.

I totally forgot that fat would cause problems if her liver was ill too. Poor little love! She sure is lucky to have you doulamamma. What did the chinese herbalist say? I know they have good herbs for toning the liver but only know adults (with alcohol problems) who've used them, don't know if they'd be too strong for littlies.
