Those are the best
Buy a stash. Down here I can find them at health food stores, Publix and Exkerds. Online I've found them at
www.earthbaby.com. THEY ARE THE BEST.
Hylands.com can also give you local stores. I also encourage the Hylands Kids Kit and a good book about Homeopathy. We've had lots of luck for all kinds of things with the kit.
Good luck and good thinking.
