The only thing that you need to worry about are the heavy metals that can be found in the fish oil. Yes, they are even in the oil. Just give her lots of water today to try to flush it out. There is also a bit of vitamin A, c and E in them as well, just naturally occurring. But these are all non toxic for the most part. The worst that could happen is she'll have a bit of diarhea. Keep a close eye on her, and maybe give a nateuropathic dr a call, they'll know more than a pediatrician when it comes to those kinds of things. Just my 2C
