my youngest is the only one of ours that got thrush -- but i remember having to poil everything several times. i know it's easy to keep it once they have it -- so out dr. told us it was importnat to keep everything very clean. (which was harder than it sounded with 2.5 yr old twins walking around) so my 2 cents it to do it as often as she's having them in her mouth. you might just keep out a couple at a time and rotate them out. H. that helps some.
