Little girl is 9 1/2 week and has oral thrush the past week treatment started yesterday due to prescription mixed up. How can babies get it? She doesn't use a dummy and bottles are used within 8 hours off being sterilized. No one at homme is suffering from it and all clothes are washed separate at 60 degrees :/ do babies just get it with out cause or is there something we are missing ? I used dentinox colic drops and calpol saline spray could these have done it ?
