Infants Less Than Six Months of Age
For infants less than 6 months of age, limiting exposure to direct sunlight is the best way to
protect them. 

• When possible, keep your infant out of direct sunlight when the sun’s rays are the strongest (between 10 a.m. and 4 p.m.).
• When outside, try to keep your infant in the shade, whether under a tree, or by using an umbrella or stroller canopy.
  Use hats with brims that shade your infant’s face and ears.
  Sunscreen can be used sparingly on infants under 6 months of age if shade
  is not possible. 

Children Over Six Months of Age
For children over 6 months of age, in addition to limiting sun exposure, sunscreen should be used to help protect them from the sun.

• Choose a sunscreen, preferably waterproof, with a protection level of at least SPF 15.  Make sure the sunscreen is “broad-spectrum,” meaning it blocks both UVB and UVA rays.  Before applying the sunscreen to all exposed areas, apply a small amount to a test area to look for a reaction.  Sunscreen should always be applied carefully around the eyes.
• The sunscreen should be applied approximately 30-45 minutes prior to exposure to allow time for the product to activate.  Sunscreen should be
  re-applied every two hours or immediately after swimming if a
  non-waterproof formulation is used.
• Use sunscreen even on cloudy days because the sun’s rays still pass through clouds.  Additionally, the sun’s rays can bounce back from surfaces such as sand and concrete, so use particular caution in these areas.
• Zinc Oxide is a very effective sun block and can be used as extra protection on the nose, cheeks, tops of the ears, and shoulders.
