Quick questions oh knowledgeable ones:

If the baby has a yeasty diaper rash (and a yeasty rash in the folds of
her neck) does this mean she also has thrush in her mouth? I know that
thrush is possible without seeing those white dots. Baby and mom
previously had thrush in diaper area and nipples respectively. Baby has
the rash again but mom is currently symptom free, but wants to treat
nipples and baby's mouth "just in case." Thoughts?

TIA,
Julie
