Yeast Is Behind Thrush and Certain Kinds of Diaper Rash

Baby Yeast Infections

Yeast infections often appear after your baby has had a round of antibiotics, and show up differently depending on where they are on your baby's skin. Thrush appears on the tongue and mouth, and looks like dried milk, while a yeast diaper rash is bright red, often with small red pimples at the rash edges. Talk to your pediatrician: Thrush is treated with an anti-yeast liquid medicine, while an anti-fungal cream is used for a yeast diaper rash.
