Maybe even check at your chemist too - you never know what they might have. Or you could get it online. When are you going to Wagga again? the other thing is make sure that you wash your hands and her hands like a woman possessed and change her linen frequently. It's a persistent beggar of a bacteria and vigilence is the key to beating it. Also boost her immune system by giving her some probiotics if you can get some locally - even inner health plus for kids from the chemist would be better than nothing at all and get some live culture yoghurt or yakult for her to drink. These infections can take hold if the immune system is already stressed or run down, so building it back up again will help her to fight it as well.
