For children older than 1, take your cue from kids who live in Hawaii and spend a lot of time at the beach: swim shirts (rash guards) are a must! These nylon/spandex shirts and bodysuits are the best way to protect sensitive skin.
Consider applying a complete sunblock, such as zinc, to a child’s nose, under the eyes, on the back of the neck, and on the tops of the ears. (This is in addition to the waterproof SPF 30 sunscreen they should already be wearing.)
Do Sunscreen Right
Get to know the American Academy of Pediatrics' guidelines on sunscreen use, which include wearing hats, sunglasses, and cover-ups, minimizing sun exposure between 10 a.m. and 4 p.m., and pausing every two hours, or after swimming or sweating, to reapply sunscreen of SPF 15 or greater that protects against both UVA and UVB rays. (NOTE: Hawaii may soon ban the sale and distribution of any sunscreens containing oxybenzone and octinoxate, which scientists say damage reefs. Here are some other options - https://www.mauireefs.org/wp-content/uploads/2018/01/MNMRC-Be-Sunscreen-Smart.pdf )
Choose to set up near the Lifeguard stand
Ask about wave conditions – rip currents and shore breaks
Arrive Early – the beach is more pleasant before the wind picks up
Older kids also run the risk of dehydration. Make sure they drink LOTS of water or non-caffeinated juice throughout the day. Avoid soda.
No diving until you know the depth even if you see others diving there
Even if your child can swim, always keep close eye on them in the water
Look but don’t touch marine life
Take frequent breaks - Exhaustion, sunburn, hypothermia, heat stroke and more are all common problems when spending time at the beach by the water all day long. Set your watch and take a short break every hour.
