Summer has arrived, which means children will be playing outside even more. This means parents will have to ramp-up their strategies for keeping their children safe.

Everyone knows that kids can seem invisible. That's why before starting your car, look around to make sure no youngsters are behind your vehicle.

It is well known how fast children can move and especially without their parents noticing where they are going. Therefore, always stay within touching distance of your kids, especially if there's water nearby.

"Parents need to be aware of where there kids are and where they are swimming and to be in close contact and be able to rescue them if something unforeseen should happen," said Dr. Gerry Gardner, chairman of American Academy of Pediatrics.

If you own a pool, a fence should be built around the pool, and the gate locked. Teach your children to swim by age four, but don't use a child's ability to swim or their flotation devices as an excuse not to watch them.

Always be vigilant about making a child wear a helmet while biking, skating or skateboarding.

Also, keep them away from power tools, especially lawnmowers.

Children play hard, so when it's hot outside it's important to make sure they stay properly hydrated.

"When we are giving children lots of liquids in the summer, we should pay attention to the kinds of liquids we are giving them," Gardner said.

Kids should drink plenty of water. Avoid drinks with caffeine, sugar, high fructose corn syrup even artificial sweeteners.

Keep in mind that although summer is fun, it's potentially the most dangerous season in which children could be injured.
