In general, infants' skin is much thinner and more sensitive to the sun than adults' skin, even in individuals with darker complexion. The amount of sunscreen needed depends on how light the complexion of the child, but I would recommend using sunscreen with an SPF of 30 or greater for very fair-skinned children. Sunscreen is most effective if first applied 30 minutes before sun exposure. Use sunscreen whenever you expect to be in the sun for thirty minutes or more, and re-apply after swimming. This is a wonderful time of the year.
Most children love to be outdoors.
By all means, take your children outdoors and enjoy the summer fun. While you are giving your children a good time, you can also give them the gift of future good health by being careful. Protecting your children's eyes from the dangerous rays of the sun and protecting their skin from sunburns is a gift that will last their whole lives. This is not a substitute for medical care or your doctor's attention. Please seek the advice of your pediatrician or family doctor.
