This picture shows the classic signs of a baby with a yeast diaper rash:

Yeast infections can commonly complicate other diaper rashes.

You should suspect that a diaper rash might be caused by yeast (Candida) when your baby's regular diaper rash just isn't getting better with your usual diaper rash ointments and creams.

Another good sign of a yeast diaper rash is when a diaper rash becomes bright red, and is surround with red bumps (satellite lesions).

Treatments for yeast diaper rashes typically include the use of topical antifungal skin creams, such as Nystatin or Vusion.
