Move your baby to the shade or under a tree, umbrella, or the stroller canopy. Dress your baby in clothing that covers the body, such as comfortable lightweight long pants, long-sleeved shirts, and hats with brims that shade the face and cover the ears. Select clothes made of tightly woven fabrics. If you're not sure about how tight a fabric's weave is, hold the clothing up to a lamp or window and see how much light shines through. The less light, the better.
Clothing made of cotton is both cool and protective.
When using a cap with a bill, make sure the bill is facing forward to shield the baby's face. Child-sized sunglasses with UV protection are also a good idea for protecting your child's eyes. The sun's rays are the strongest between 10 am and 4 pm. Try to keep your baby out of the sun during these hours. A suntan is good for your baby.
