A. hi dear A drool rash can appear around the mouth and cheeks, in the folds of your baby's neck, and on your baby's chest as a result of too much saliva causing wet skin. Drool rashes typically present as flat or slightly raised patches with small red bumps. They can also have a chapped appearance.
