LOL! Diane, you're right - getting my child to eat any cabbage, let alone fermented would be a chore!
I too discovered the Renew Life probiotics at my nfs recently and am thinking about ordering some ... for me!
Their children's version (the chewable), contains one of the things on my son's "can't have" list (citric acid, I think). The brand we used to use now has dairy in it, thanks to the new labeling laws, I'm sure.
ETA: ok, now I clicked on your link and see that the probiotic you mentioned is for children 1 and up! I'll have to look for that one at my Whole Foods. I was disappointed to see that iherb.com doesn't carry it (unless I just couldn't find it). They do have the UltimateFlora Critical Care, but its pretty expensive (and for adults)! Anyone know if its ok to just dump the powder out of the capsule for a child that doesn't swallow pills yet?
