Exactly what Debbie said. I do still use it though for small accents or small cookies...they say it is non-toxic but apparently your digestive system does not break it down at all and it passes right through the system...
When I first started using it a couple of years ago, I made cookies for a friend's son's 1st birthday...she called me the next day to thank me as well as share that he son had sparkly-poo (sorry for the TMI, but just thought I'd share).
I think it boils down to preference.
