Temperature rising: Heat rash

When a baby overheats, due to the temperature or fever for example, you may see a rash on the baby's upper body. The rash may appear quickly and show up as clear or red raised bumps on your baby's skin.

Once the baby cools down, the rash usually disappears on its own.

In general, babies aren't very good at sweating yet so they can overheat more easily than an adult. 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.
