It depends on the age and the size of the child. But neither are needed, the haste or strength in which you blow is not of importance.
If you are not certain on the amount of air you should breathe into a child, open up/rip open the shirt and watch the chest move up and down to determine a proper amount of air.
Do not "force" the air when giving CPR to an infant! With force, I mean the way it feels when you're blowing too much air into a balloon.
Cover the mouth AND nose of the infant with your mouth. Blow in a gentle breath. Remember to kept the baby's head at a neutral position as to not overstretch the trachea. Call for help if you have not already done so. Do the breaths with compressions just like an adult except with two fingers on the chest only.
When giving rescue breaths, blow slowly and steadily with good head position. This technique minimizes air in the stomach.To minimize air entering the stomach make sure the head is well tipped back, and dont blow too hard or too long
Blow hard, and take good breaths.
Rescue breaths are no longer generally in use. Rapid chest-pressure respiration is now recommended as being more effective. But, if it turns out that you must do rescue breathing, blow a breath of air into the victim until her chest raises 2 inches or so, then immediately let the air out. If you meant for how long to keep doing rescue breathing, you only stop when the victim starts breathing on his own, or you are just too exhausted to continue.
The standard when the heart has stopped is to first blow twice then press the heart 30 times in 15 seconds (twice per second), then blow two times, and repeat with 30 compressions. The two important things are: Remember that the heart-rate of infants is high, thus the quick pressing on the chest and remember not to inflate with more air than a mouthful. You may check this with your hand. If you breath in too much, a lung could rupture or the stomach is filled with air.

The two preferred methods to administer mouth-to-mouth are the head-tilt/chin lift method and the jaw thrust method. A third method called the head-tilt/neck-lift is not recommended any longer because of the potential for spinal cord injuries.
Because the poor children at the bus stop will blow away:)
Sheltering indoors is safest; winds can blow damaging debris your way.
When giving rescue breaths to a child, you should give 1 breath about every 3 seconds. For CPR, the ratio is 30:2 which means for every 30 chest compressions you will give 2 rescue breaths (ventilations).
it should blow directly to the condenser
Check out ProCPR's Free CPR Training Video Library at the related link. There, you'll find high quality video demonstrations for CPR. First determine if the patient has signs of life; open airway head tilt chin lift method. If no signs of life, give 2 breaths. Now it is time to start the CPR cycles. Give 30 compressions, followed by 2 breaths. Repeat 30 compressions / 2 breaths until EMS arrives to take over. Check for pulse. Give 2 rescue breaths. Give 30 chest compressions. See related links
