I'm wondering if anyone has helpful advice about how to rid myself of a lingering thrush problem that's persisted for months now. I use a vinegar solution topically, and that seems to really keep it in check, but it's always lingering.... I need to fix the underlying problem, I'm presuming, and I don't know how to start. It hasn't been bad, just annoying. It doesn't appear to be affecting either child, either. I'd be very grateful to hear any suggestions.
