Heat rash
Previous Next 5 of 6 Heat rash

Heat rash appears as fine, clear or red spots on your baby's skin. Heat rash is common in babies during hot, humid weather — often a result of overdressing.

Heat rash generally disappears on its own. In the meantime, move the baby to a cooler environment or give the baby a cool bath. To prevent heat rash in hot weather, dress your baby in cool, lightweight clothing. In cold weather, dress your baby in layers so that you can remove items if the temperature rises.
