It is never too early to protect babies from the sun!
Babies are not born with a developed skin protection system and have sensitive skin that is thinner than adult skin so they burn more easily. A young child has more skin, relative to body mass, than an adult, so a sunburn will be more serious. Even children born to parents with deeply pigmented (dark) skin require maximum protection. Sunburns not only hurt and cause skin damage but they can also cause dehydration and fever.
