At what age is it safe to put sunscreen on a baby?
Your baby's skin is sensitive and can easily absorb too many chemicals, so avoid sunscreens before the baby is 6 months of age, except those with zinc oxide as the only active ingredient, and use on small areas of her body. Use clothing plus shade as the primary method of protection. Provide additional protection by keeping her out of the sun as much as possible: take walks before 10 a.m. or after 4 p.m., when UVB rays aren't as intense; use a stroller canopy; dress her in lightweight clothing that covers her arms and legs; and choose a wide-brimmed hat or bonnet that covers her face, ears, and neck.
