Playing in the sun
Older children:
The best defence against the sun is covering up. Wear a hat with a three-inch brim or a shade facing forward, sunglasses (look for sunglasses that block ultraviolet rays), and cotton clothing with a tight weave. Stay in the shade whenever possible, and avoid sun exposure during peak intensity hours (from 10 a.m. and 4 p.m.). The risk of sunburn increases at higher altitudes.
Sunscreen with an SPF (sun protection factor) of 15 should be effective for most people. Be sure to apply enough sunscreen. Reapply sunscreen every two hours, or after swimming or sweating. Creams or baby oil may make the skin look shiny and soft, but they provide no protection from the sun.
Young children:
Babies under 6 months of age should be kept out of direct sunlight, in the shade.
Dress babies in light clothing that covers the arms and legs.
Apply sunscreen at least 30 minutes before going outside, and use sunscreen even on cloudy days.
Swimming pool safety
Safety tips for children while swimming.
Never leave children alone in or near the pool.
Make sure an adult trained in life-saving techniques is close at hand.
Avoid inflatable swimming aids such as "floaties." They are not a substitute for approved.
Life vests and can give children a false sense of security.
Children are not developmentally ready for swimming lessons till 4 years of age.
Bicycle safety tips
Do not push your child to ride a 2-wheeled bicycle until he is ready, at about age 5 or 6. Consider the child's coordination and desire to learn to ride. Stay with support wheels on both sides until your child is older and more experienced.
Take your child with you when you shop for the bike, so that he can try it out. The value of a properly sized bike far outweighs the value of surprising your child with a new bike.
Buy a bike that is the right size, not one your child has to "grow into". Over-sized bikes are especially dangerous.
Test the bicycle for proper fit
Sitting on the seat with hands on the handlebar, your child must be able to place the balls of both feet on the ground.
Straddling the center bar, your child should be able to stand with both feet flat on the ground with about a 1-inch clearance between the crotch and the bar.
When buying a bike with hand brakes for an older child, make sure that the child can comfortably grasp the brakes and apply sufficient pressure to stop the bike. A helmet should be standard equipment.
