We use the low or nonfat Stonyfield yogurt. Both of my furbabies like it, thank goodness! If your baby won't eat it, you can mix in something that they will like...Examples, little pieces of apple (peeled) or something that they really like (no meat though
)
Denosyl (Sam-E) also makes their tummies upset sometimes. There's something called Nux Vomica that you can get at a health food store. Just drop 1 or 2 beads into their mouth without touching the beads so they don't lose their potency. It helps with the nausea.
Are you giving the right amount of milk thistle? I have a chart that I found on the liver shunt/mvd group that explains how much you can give of the milk thistle per their weight. Maybe she's getting too much? I will get that to you as soon as I find it.
