A naturopath would have far greater access to decent probiotics - Nicole Tracy the BB naturopath is brilliant and based in a few locations, East Melbourne and Park Orchards. Some members were talking about this in another thread about babies getting sick alot, I think they recommended Baby Biotics? Or something like that. Hopefully one of them will post but its a cold winters night on a Sunday, you might have to wait a little for a reply! You could also get Fast Tract which is a bit more exxy but very potent and organic, gluten free. They deliver very fast. Great for the whole family.
