Warm weather is here, and as the sun's rays grow stronger, it's important to protect your children's delicate skin. According to NBC, sunscreen is a nonnegotiable for all kids older than 6 months old, regardless of their skin tone. Sunscreen "helps prevent sun damage that goes beyond painful sunburns and can reduce the risk of skin cancer later in life," Dr. Rebecca Carter, a pediatrician at the University of Maryland Children's Hospital, told the news network.
