Q: Do I need to take steps to protect my infant from sun damage year-round?

A: Absolutely. Protection from sun damage should be a top priority whenever you're outside. With prolonged and unprotected exposure to the sun's rays, permanent damage can occur and may be a precursor to dangerous malignant melanoma, a type of skin cancer. During infancy, hats with brims or visors are recommended year-round, even in carriages or strollers with awning-style tops to protect skin and eyes. Applied sunscreens aren't recommended for infants' skin before age six months. So exercise "mother wit" caution and avoid direct and prolonged exposures. Once your baby is six months old, it's safe to apply protective sunscreens. I recommend one with a sun protective factor (SPF) of at least 30 that blocks both UVA and UVB rays. Depending upon your geographic area and the time of year, you will have to determine the frequency for reapplication. When possible, avoid the sun when it's at its strongest, between 11 a.m. and 2 p.m.
